Dialogflow Fulfilment webhook call failed

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',
from: '2019-12-31',
to: '2020-12-12',
page: 2
}
).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
{
"responseId": "a871b8d2-16f2-4873-a5d1-b907a07adb9a-b4ef8d5f",

And Here is fulfillment request:

"synthesizeSpeechConfig": {
"speakingRate": 1,
"voice": {}
}
}
}
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

DynamoDB InvalidParameterType Error While Trying To Put A New Item

I am trying to implement a DynamoDB based application to store some request data. I read the DynamoDB official documentation and currently I am following this official tutorial to do some basic operations.
I am using a local DynamoDB docker container. You can run it with this:
docker run -d -p 8000:8000 amazon/dynamodb-local:latest -jar DynamoDBLocal.jar -sharedDb
When I try to create a new table just same as the tutorial I gave above, I got no error, everything is fine:
var params = {
TableName: 'book',
KeySchema: [
{
AttributeName: 'title',
KeyType: 'HASH',
}
],
AttributeDefinitions: [
{
AttributeName: 'title',
AttributeType: 'S'
}
],
ProvisionedThroughput: {
ReadCapacityUnits: 1,
WriteCapacityUnits: 1,
}
};
dynamodb.createTable(params, function(err, data) {
if (err) print(err); // an error occurred
else print(data); // successful response
});
But when I try to put some new items in it:
var params = {
TableName: 'book',
Item: { // a map of attribute name to AttributeValue
title: "Sample Application: CloudList",
chapter: 10
}
};
dynamodb.putItem(params, function(err, data) {
if (err) print(err); // an error occurred
else print(data); // successful response
});
I got this error:
31 validation error actually is equal to number of chars in title: Sample Application: CloudList. DynamoDB shell also did not recognized the print function which is given in the above tutorial. So I had to replace it with ppJson function. Where am I doing wrong and how can I put/delete/get items from DynamoDB via Web Shell? (and also via PHP code)
Edit: I also tried what Vikdor said in the comment, it seems I got rid of that UnexpectedParameter error but this time I got Invalid attribute value type error.
var params = {
TableName: 'book',
Item: { // a map of attribute name to AttributeValue
'title': {S: "Sample Application: CloudList"},
'chapter': {N: '10'}
}
};

This doc explains the structure of the Item key in the params passed to the API and your params should be as follows:
var params = {
TableName: "book",
Item: {
"title": {"S": "Sample Application: CloudList"},
"chapter": {"N": :10"}
}
};
Note that even the numbers should be enclosed in quotes.

Saving an object to DynamoDB instance via NodeJS

I feel like I'm missing something obvious, but the documentation is a bit confusing for DynamoDB, especially for NodeJS (I do see a lot for Java, however!).
I've done quite a bit of searching and only have found questions pertaining to the old SDK, so hopefully this isn't a duplicate question!
I'm trying to store a Javascript object into my DynamoDB instance. The error I'm getting and the code I'm using is outlined below.
Error:
Unable to add item. Error JSON: {
"message": "One or more parameter values were invalid:
Type mismatch for key File expected: S actual: M",
"code": "ValidationException",
"time": "2016-10-29T19:36:02.317Z",
"requestId": [removed],
"statusCode": 400,
"retryable": false,
"retryDelay": 0
}
Code:
var aws = require('aws-sdk');
var docClient = new aws.DynamoDB.DocumentClient({
"accessKeyId": AWS_ACCESS_KEY_ID,
"secretAccessKey": AWS_SECRET_ACCESS_KEY,
region: 'us-east-1',
endpoint: "https://dynamodb.us-east-1.amazonaws.com"
});
var tableName = AWS_TABLE_NAME;
var params = {
TableName: tableName,
Item: {
ProjID: projID,
File: {
name: fileName,
url: fileUrl
}
}
};
docClient.put(params, function (err, data) {
if (err) {
console.error("Unable to add item. Error JSON:", JSON.stringify(err, null, 2));
} else {
console.log("Added item:", JSON.stringify(data, null, 2));
}
callback(true);
});
Once again, I'm sure it's a fairly simple issue - I just haven't quite found any documentation to help me out that's updated.
Thanks in advance for any help you can give!

Is File an attribute in the schema of your table? If it is and it's defined as a String, then the error you are getting is just indicating that you are trying to put a map into a string attribute.
DynamoDB only supports String and Numeric keys so you'll have to revisit your design. Perhaps you can store the File information as a string for the key and then expanded as a map into a separate attribute if need be.

gapi.client.gmail.users.labels.create gives invalidArgument error

I am working on creating labels using JavaScript Gmail API.
function createLabel(userId, newLabelName, callback) {
var request = gapi.client.gmail.users.labels.create({
'userId': userId,
'label': {'name': newLabelName}
});
request.execute(callback);}
This is the code of Developer API Example
I am able to authenticate and even I'll get the label list but while creating the label I am getting the below error.
{
"error": {
"errors": [
{
"domain": "global",
"reason": "invalidArgument",
"message": "Invalid request"
}
],
"code": 400,
"message": "Invalid request"
}
}
But when I am using the Try It example It's working but only difference is it's do the POST request with key={Your auth key} which the example provided won't attach that part to URL.

The data you send should be in the resource-parameter, and labelListVisibility and messageListVisibility are also mandatory fields:
function createLabel(userId, newLabelName, callback) {
gapi.client.gmail.users.labels.create({
userId: userId,
resource: {
name: newLabelName,
labelListVisibility: 'labelShow',
messageListVisibility: 'show'
}
}).execute(callback);
}

Error every time I run datastore.runQuery: one of fields Query.query and Query.gql_query must be set

I'm trying to run a simple query against my Google Cloud datastore using google-api-nodejs-client. I want to query for all entities matching a given kind. When I run this query using the "Try it now" tool it works fine:
Request
POST https://www.googleapis.com/datastore/v1beta2/datasets/healthier-staging/runQuery?key={YOUR_API_KEY}
{
"query": {
"kinds": [
{
"name": "Subscriber"
}
]
}
}
Response
200 OK
{
"batch": {
"entityResultType": "FULL",
"entityResults": [
{
"entity": {
"key": {
"partitionId": {
"datasetId": "s~healthier-staging"
},
"path": [
{
"kind": "Subscriber",
"name": "+1215XXXXXXX"
}
]
},
"properties": {
...
I'm able to authenticate using my credentials, create a transaction, etc. so I know it's not an authentication issue.
Here's the code I'm trying to run in Node:
this.datastore.runQuery({
datasetId: 'healthier-staging',
query: {
kinds: [{name: 'Subscriber'}]
},
}, (function(err, result) {
if (err) {
console.error(err);
return;
}
}).bind(this));
When I try to run the same query using the Node module, I get this error:
{ [Error: one of fields Query.query and Query.gql_query must be set]
code: 400,
errors:
[ { domain: 'global',
reason: 'INVALID_ARGUMENT',
message: 'one of fields Query.query and Query.gql_query must be set' } ] }
This doesn't make sense, since I've specified the query field. I've tried all sorts of things: removing datasetId (produces an error about needing datasetId), using gql_query instead (same error), encapsulating the datasetId inside a transaction and passing that along inside readOptions, etc.
Is this a bug or am I doing something silly?
Thanks!

I mentioned this on your other StackOverflow question, but your request should be included in the resource section:
this.datastore.runQuery({
datasetId: 'healthier-staging',
resource: {
query: {
kinds: [{name: 'Subscriber'}]
},
},
}, (function(err, result) {
if (err) {
console.error(err);
return;
}
}).bind(this));
