Dialogflow Fulfilment webhook call failed - javascript

I am new to dialogflow fulfillment and I am trying to retrieve news from news API based on user questions. I followed documentation provided by news API, but I am not able to catch any responses from the search results, when I run the function in console it is not errors. I changed the code and it looks like now it is reaching to the newsapi endpoint but it is not fetching any results. I am utilizing https://newsapi.org/docs/client-libraries/node-js to make a request to search everything about the topic. when I diagnoise the function it says " Webhook call failed. Error: UNAVAILABLE. "
'use strict';
const functions = require('firebase-functions');
const {WebhookClient} = require('dialogflow-fulfillment');
const {Card, Suggestion} = require('dialogflow-fulfillment');
const http = require('http');
const host = 'newsapi.org';
const NewsAPI = require('newsapi');
const newsapi = new NewsAPI('63756dc5caca424fb3d0343406295021');
process.env.DEBUG = 'dialogflow:debug';
exports.dialogflowFirebaseFulfillment = functions.https.onRequest((req, res) =>
{
// Get the city
let search = req.body.queryResult.parameters['search'];// search is a required param
// Call the weather API
callNewsApi(search).then((response) => {
res.json({ 'fulfillmentText': response }); // Return the results of the news API to Dialogflow
}).catch((xx) => {
console.error(xx);
res.json({ 'fulfillmentText': `I don't know the news but I hope it's good!` });
});
});
function callNewsApi(search)
{
console.log(search);
newsapi.v2.everything
(
{
q: 'search',
langauge: 'en',
sortBy: 'relevancy',
source: 'cbc-news',
domains: 'cbc.ca',

}
).then (response => {console.log(response);
{
let articles = response['data']['articles'][0];
// Create response
let responce = `Current news in the $search with following title is ${articles['titile']} which says that
${articles['description']}`;
// Resolve the promise with the output text
console.log(output);
}
});
}
Also here is RAW API response

Also here is the screenshot from the firebase console.
Can anyone guide me what is that I am missing in here?

The key is the first three lines in the error message:
Function failed on loading user code. Error message: Code in file index.js can't be loaded.
Did you list all required modules in the package.json dependencies?
Detailed stack trace: Error: Cannot find module 'newsapi'
It is saying that the newsapi module couldn't be loaded and that the most likely cause of this is that you didn't list this as a dependency in your package.json file.
If you are using the Dialogflow Inline Editor, you need to select the package.json tab and add a line in the dependencies section.
Update
It isn't clear exactly when/where you're getting the "UNAVAILABLE" error, but one likely cause if you're using Dialogflow's Inline Editor is that it is using the Firebase "Spark" pricing plan, which has limitations on network calls outside Google's network.
You can upgrade to the Blaze plan, which does require a credit card on file, but does include the Spark plan's free tier, so you shouldn't incur any costs during light usage. This will allow for network calls.
Update based on TypeError: Cannot read property '0' of undefined
This indicates that either a property (or possibly an index of a property) is trying to reference against something that is undefined.
It isn't clear which line, exactly, this may be, but these lines all are suspicious:
let response = JSON.parse(body);
let source = response['data']['source'][0];
let id = response['data']['id'][0];
let name = response['data']['name'][0];
let author = response['author'][0];
let title = response['title'][0];
let description = response['description'][0];
since they are all referencing a property. I would check to see exactly what comes back and gets stored in response. For example, could it be that there is no "data" or "author" field in what is sent back?
Looking at https://newsapi.org/docs/endpoints/everything, it looks like none of these are fields, but that there is an articles property sent back which contains an array of articles. You may wish to index off that and get the attributes you want.
Update
It looks like that, although you are loading the parameter into a variable with this line
// Get the city and date from the request
let search = req.body.queryResult.parameters['search'];// city is a required param
You don't actually use the search variable anywhere. Instead, you seem to be passing a literal string "search" to your function with this line
callNewsApi('search').then((output) => {
which does a search for the word "search", I guess.
You indicated that "it goes to the catch portion", which indicates that something went wrong in the call. You don't show any logging in the catch portion, and it may be useful to log the exception that is thrown, so you know why it is going to the catch portion. Something like
}).catch((xx) => {
console.error(xx);
res.json({ 'fulfillmentText': `I don't know the news but I hope it's good!` });
});
is normal, but since it looks like you're logging it in the .on('error') portion, showing that error might be useful.

The name of the intent and the variable I was using to make the call had a difference in Casing, I guess calls are case sensitive just be aware of that

GET request to webpage returns string, but cannot use it

I am creating a google chrome extension, and when I make a get request to this web page https://www.rightmove.co.uk/property-for-sale/find.html?locationIdentifier=REGION%5E27675&maxBedrooms=2&minBedrooms=2&sortType=6&propertyTypes=&mustHave=&dontShow=&furnishTypes=&keywords=, I get the webpage HTML as a response which is what I want (the website I am requesting info from does not have an API and I cannot web scrape for reasons too long to explain here). This response comes in the form of a string. When I attempt to split this string at a certain point, bis_skin_checked, I am returned an array of length 1, meaning that there was no match and nothing has been split. But when I look at the string returned it has it included.
I have tried things like removing spaces and carriage returns but nothing seems to be working. This is my GET request code:
function getNewPage(url) {
let returnedValue = fetch(url, {
method: 'GET',
headers: {
'Content-Type': 'text/html',
},
})
.then(response => response.text())
.then(text => {
return text
})
return returnedValue
}
I then go on to resolve the promise which is returnedValue:
let newURL = getHousePrices(currentUrl) // Get Promise of new page as a string
newURL.then(function(value) { // Resolve promise and do stuff
console.log(value.split('bis_skin_checked').length)
})
And then work with the string which looks like this: (I have attached an image as I cannot copy the text from the popup)
Image Link To API Request return
I'm assuming you want to get the home values, given certain search parameters.
Scraping raw text is usually not the way to go. I took a look at the site and saw it uses uniform network requests that you can modify to capture the data you need directly instead of scraping the raw HTML.
I built a solution that allows you to dynamically pass whatever parameters you want to the getHomes() function. Passing nothing will use the default params that you can use as a baseline while you try to adjust the request for any additional modifications/use cases.
Install the below solution and run getHomes() from the service worker.
Here's a brief video I made explaining the solution: https://vimeo.com/772275354/07fd1025ed

const newParams = passedParams ? passedParams : {}; // set to an empty object if no new params passed - avoid error in object.entries loop.

// we iterate through each key in our default params to check if we passed a new value for that key.
// we then set the params object to the new value if we did.
if (newParams[key]) params[key] = newParams[key];
});
const rightMoveAPISearch = `https://www.rightmove.co.uk/api/_search?

`.replace(/\s/g, ''); // removes the whitespaces we added to make it look nicer / easier to adjust.
const data = await
fetch(rightMoveAPISearch, {
"method": "GET",
})
.then(data => data.json())
.then(res => { return res })
if (data.resultCount) {
console.log('\x1b[32m%s\x1b[0m', 'Request successful! Result count: ', parseInt(data.resultCount));

console.log('Properties: ', data.properties);
}
else console.log('\x1b[31m%s\x1b[0m', `Issue with the request:`, data)

Hope this is helpful. Let me know if you need anything else.

My Query Quagmire: My node.js program works just fine, except when I try to execute queries, or filtered HTTP requests. Why?

I have been working on the backend of my app. At this point, it can access all data in a data base, and output it. I'm trying to implement some queries, so that the user can filter out the content that is returned. My DAL/DAO, looks like this
let mflix //Creates a variable used to store a ref to our DB
class MflixDAO {
static async injectDB(conn){
if(mflix){
return
}
try{
mflix = await conn.db(process.env.JD_NS).collection("movies")
}catch(e){
console.error('Unable to establish a collection handle in mflixDAO: ' + e)
}
}
// Creates a query to fetch data from the collection/table in the DB
static async getMovies({
mflix.controller
filters = null,
page = 0,
moviesPerPage = 20,
} = {}) {
let query
if (filters){
// Code
if("year" in filters){
query = {"year": {$eq: filters["year"]}}
}
// Code
}
// Cursor represents the returned data
let cursor
try{
cursor = await mflix.find(query)
}catch(e){
console.error('Unable to issue find command ' + e)
return {moviesList: [], totalNumMovies: 0}
}
const displayCursor = cursor.limit(moviesPerPage).skip(moviesPerPage * page)
try{
const moviesList = await displayCursor.toArray() // Puts data in an array
const totalNumMovies = await mflix.countDocuments(query) // Gets total number of documents
return { moviesList, totalNumMovies}
} catch(e){
console.error('Unable to convert cursor to array or problem counting documents ' + e)
return{moviesList: [], totalNumMovies: 0}
}
}
}
export default MflixDAO
Just so you know, I am using a sample database from MongoDB Atlas. I am using Postman to test HTTP requests. All the data follows JSON format
Anyway, when I execute a basic GET request. The program runs without any problems. All the data outputs as expected. However, if I execute something along the lines of
GET http://localhost:5000/api/v1/mflix?year=1903
Then moviesList returns an empty array [], but no error message.
After debugging, I suspect the problem lies either at cursor = await mflix.find(query) or displayCursor = cursor.limit(moviesPerPage).skip(moviesPerPage * page), but the callstacks for those methods is so complex for me, I don't know what to even look for.
Any suggestions?
Edit: Here is an example of the document I am trying to access:

EDIT: It seems to be a datatype problem. When I request a data with a string/varchar type, the program returns values that contain that value. Example:
Input:
GET localhost:5000/api/v1/mflix?rated=TV-G
Output:
{
"_id": "XXXXXXXXXX"
// Data
"rated" = "TV-G"
// Data
}
EDIT: The problem has nothing to do with anything I've posted up to this point it seems. The problem is in this piece of code:
let filters = {}
if(req.query.year){
filters.year = req.query.year // This line needs to be changed
}
const {moviesList, totalNumMovies} = await MflixDAO.getMovies({
filters,
page,
moviesPerPage,
})
I will explain in the answer below
Ok so the problem, as it turns out, is that when I make an HTTP request, the requested value is passed as a string. So in
GET http://localhost:5000/api/v1/mflix?year=1903
the value of year is registered by the program as a string. In other words, the DAO ends up looking for "1903" instead of 1903. Naturally, year = "1903" does not exist. To fix this, the line filters.year = req.query.year must be changed to filters.year = parseInt(req.query.year).

What is wrong with my JSON output for a Slack Message payload?

I have set up what I think should be a working JSON output to send a message in slack but Slack keeps rejecting it.
I have tried multiple different message layout formats using the guides on slack's api site, but so far the only method that has successfully sent is a fully flat JSON with no block formatting.
function submitValuesToSlack(e) {
var name = e.values[1];
var caseNumber = e.values[2];
var problemDescription = e.values[3];
var question = e.values[4];
var completedChecklist = e.values[5];
var payload = [{
"channel": postChannel,
"username": postUser,
"icon_emoji": postIcon,
"link_names": 1,
"blocks": [
{
"type": "section",
"fields": [
{
"type": "mrkdwn",
"text": "*Name:*\n " + name
}
]
}]
}];
console.log(JSON.stringify(payload, null, "\t"));
var options = {
'method': 'post',
'payload': JSON.stringify(payload)
};
console.log(options)
var response = UrlFetchApp.fetch(slackIncomingWebhookUrl, options);
}
When I run this, I get the following output:
[
{
"channel":"#tech-support",
"username":"Form Response",
"icon_emoji":":mailbox_with_mail:",
"link_names":1,
"blocks":[
{
"type":"section",
"fields":[
{
"type":"mrkdwn",
"text":"*Name:*\n test"
}
]
}
]
}
]
Which I believe is correct, however slack api just rejects it with an HTTP 400 error "no text"
am I misunderstanding something about block formatting?
EDIT:
To Clarify, formatting works if I use this for my JSON instead of the more complex format:
{
"channel":"#tech-support",
"username":"Form Response",
"icon_emoji":":mailbox_with_mail:",
"link_names":1,
"text":"*Name:*\n test"
}
The reason you are getting the error no_text is because you do not have a valid message text property in your payload. You either need to have a text property as top line parameter (classic style - your example at the bottom) or a text block within a section block.
If you want to put to use blocks only (as you are asking) the section block is called text, not fields. fields is another type of section bock that has a different meaning.
So the correct syntax is:
[
{
"channel":"#tech-support",
"username":"Form Response",
"icon_emoji":":mailbox_with_mail:",
"link_names":1,
"blocks":[
{
"type":"section",
"text":[
{
"type":"mrkdwn",
"text":"*Name:*\n test"
}
]
}
]
}
]
Also see here for the official documentation on it.
Blocks are very powerful, but can be complicated at times. I would recommend to use the message builder to try out your messages and check out the examples in the docu.

Rest API Patch only 1 field at a time

I'm working on an inline grid editor that calls an express rest api after a single value in the grid is updated. So when a user changes a single field in the grid, I am calling a PATCH request to update the field. However I can't figure out how to only update a single field. When I try it tries to update them all and if there's no value it makes the value NULL in the database. I want to only update a single field, and only the one passed into the API (it could be any of the fields). Here's my method to patch:
// Update record based on TxnID
router.patch('/editablerecords/update', function (req, res) {
let qb_TxnID = req.body.txnid
let type = req.body.type;
let margin = req.body.margin;
if (!qb_TxnID) {
return res.status(400).send({ error:true, message: 'Please provide TxnID' });
}
connection.query("UPDATE pxeQuoteToClose SET ? WHERE qb_TxnID = '" + qb_TxnID + "'", { type, margin }, function (error, results, fields) {
if(error){
res.send(JSON.stringify({"status": 500, "error": error, "response": null }));
//If there is error, we send the error in the error section with 500 status
} else {
res.send(JSON.stringify({ error: false, data: results, message: 'Record updated.' }));
//If there is no error, all is good and response is 200OK.
}
});
});
I will only be updating 1 field at a time, either type or margin, but not both (in this case) at the same time. If I only send one of the fields, the other field becomes null. I've tried to read up on the connection.query() method but can find no information and I don't understand how it builds the query, except that every req.body.value that is passed to it gets used to build the query.
I'm new to building this REST API and feel like I'm missing something simple.
EDIT: I'd like to add, I MAY want to update both fields, but I'd also like to update a single field at a time. Thanks
Per the RFC, the body of a PATCH call should not be the updated representation, but rather a set of instructions to apply to the resource.
The PATCH method requests that a set of changes described in the
request entity be applied to the resource identified by the Request-
URI. The set of changes is represented in a format called a "patch
document" identified by a media type.
One good proposed standard for using PATCH with JSON can be found at https://www.rfc-editor.org/rfc/rfc6902. An example patch document using that standard would be:
[
{ "op": "test", "path": "/a/b/c", "value": "foo" },
{ "op": "remove", "path": "/a/b/c" },
{ "op": "add", "path": "/a/b/c", "value": [ "foo", "bar" ] },
{ "op": "replace", "path": "/a/b/c", "value": 42 },
{ "op": "move", "from": "/a/b/c", "path": "/a/b/d" },
{ "op": "copy", "from": "/a/b/d", "path": "/a/b/e" }
]

Assistance needed with JSON

I'm creating a JSON file to hold information for commands.
The JSON file holds the trigger and repsonse for the commands, I have one in the file, but I want to add more, but when I do I get an error
{
"trigger": "twitter",
"repsonse": "https://www.twitter.com/Fhaelin"
}
{
"trigger": "test",
"repsonse": "This is a test command"
}
I get thrown errors and i dont know why
Here's the code I'm using to read it:
bot.on("message", function(message) {
var input = message.content.toLowerCase();
if (input === prefix + Commands.trigger)
{
bot.sendMessage(message, message.author + " : " + Commands.repsonse)
}
})
Whole code
http://hastebin.com/punabobisu.coffee
You get errors because that's an invalid JSON document. There can only be one top-level value in a JSON document.
To have a list of objects, put them in an array: [..., ...]:
[
{
"trigger": "twitter",
"response": "https://www.twitter.com/Fhaelin"
},
{
"trigger": "test",
"response": "This is a test command"
}
]
Side note: You have a consistent misspelling in your question: It's "response", not "repsonse". Only mentioning it because it'll come back to bite you at some stage if you actually put it in your code.
