Can't query by ID as second parameter with AWS DataStore

I am total noob to AWS, DataStore, and DynamoDB. I can't figure out why this isn't working.
If I attempt query an object related to my users ID from Cognito this seems to work. If I console log I get an array with one User.
let profile = await DataStore.query(User, (u) =>
u.id('eq', user.attributes.sub)
);
// Returns [Model]
console.log('[LOADING USER DATA]', profile);
If I attempt query an object related to my users ID like this. (as recommended by the docs). I get undefined.
let profile = await DataStore.query(User, user.attributes.sub);
// Returns undefined
console.log('[LOADING USER DATA]', profile);
Dynamo Data looks fine to me but am I using the wrong primary key ID field or something?
{
"id": "929e6e62-e3a0-4b84-b050-72c53eebda93",

What am I doing wrong?

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
(
{

}
).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

Getting username from GuildMember

When I was coding a guildMemberAdd and a guildMemberRemove I ran across an issue... So, I was wondering, how do you obtain the user's username and discriminator from when they join? as when I tried member.username and member.discriminator it logs as undefined and undefined
Code below, nothing was printed to console upon this issue:
exports.run = (client, member) => {
member.guild.channels.find(`name`, `mod-logs`).send({embed: {
"color": 8311585,
"footer": {
"text": "Bot made by: Pawxeric#0858"
},
"author": {
"name": "New Member",
"icon_url": member.avatarURL
},
"fields": [
{"name": `${member.username}#${member.discriminator}`, // logs as undefined#undefined
"value": "Joined"}
]
}});
}
Also, the code is having issues picking up anything that uses the member value. Like avatarURL, username, and discriminator. If there's something I'm missing, please share down below :3c

I think you want to get properties from a user object
<member>.user
User has username, discriminator and avatarurl.
The full object can be found on https://discord.js.org/

Optimalization of firebase query. Getting data by ids

I'm new in Firebase. I would like to create an app (using Angular and AngularFire library), which shows current price of some wares. I have list all available wares in Firebase Realtime Database in the following format:
"warehouse": {
"wares": {
"id1": {
"id": "id1",
"name": "name1",
"price": "0.99"
},
"id2": {
"id": "id2",
"name": "name2",
"price": "15.00"
},
... //much more stuff
}
}
I'm using ngrx with my app, so I think that I can load all wares to store as an object not list because normalizing state tree. I wanted load wares to store in this way:
this.db.object('warehouse/wares').valueChanges();
The problem is wares' price will be refresh every 5 minutes. The number og wares is huge (about 3000 items) so one response will be weight about 700kB. I know that I will exceed limit downloaded data in a short time, in this way.
I want limit the loading data to interesing for user, so every user will can choose wares. I will store this choices in following way:
"users": {
"user1": {
"id": "user1",
"wares": {
"id1": {
"order": 1
},
"id27": {
"order": 2
},
"id533": {
"order": 3
}
},
"waresIds": ["id1", "id27", "id533"]
}
}
And my question is:
Is there a way to getting wares based on waresIds' current user? I mean, does it exist way to get only wares, whose ids are in argument array? F.e.
"wares": {
"id1": {
"id": "id1",
"name": "name1",
"price": "0.99"
},
"id27": {
"id": "id27",
"name": "name27",
"price": "0.19"
},
"id533": {
"id": "id533",
"name": "name533",
"price": "1.19"
}
}
for query like:
this.db.object('warehouse/wares').contains(["id1", "id27", "id533"]).valueChanges();
I saw query limits in Angular Fire like equalTo and etc. but every is for list. I'm totally confused. Is there anyone who can help me? Maybe I'm making mistakes in the design of the app structure. If so, I am asking for clarification.

Because you are saving the ids inside user try this way.
wares: Observable<any[]>;
//inside ngOnInit or function
this.wares = this.db.list('users/currentUserId/wares').snapshotChanges().map(changes => {
return changes.map(c => {
const id = c.payload.key; //gets ids under users/wares/ids..
let wares=[];
//now get the wares
this.db.list('warehouse/wares', ref => ref.orderByChild('id').equalTo(id)).valueChanges().subscribe(res=>{
res.forEach(data=>{
wares.push(data);
})
});
return wares;
});
});

There are two things you can do. I don't believe Firebase allows you to query for multiple equals values at once. You can however loop over the array of "ids" and query for each one directly.
I am assuming you already queried for "waresIds" and you've stored those ID's in an array named idArray:
for id in idArray {
database.ref('warehouse/wares').orderByChild('id').equalTo(id).once('value').then((snapshot) => {
console.log(snapshot.val());
})
}
In order to use the above query efficiently you'll have to index your data on id.
Your second option would be to use .childChanged to get only the updated data after your initial fetch. This should cut down drastically on the amount of data you need to download.

Yes , you can get exactly data that you want in firebase,
See official Firebase documents about filtering
You need to get each waresID
var waresID = // logic to get waresID
var userId = // logic to get userId
var ref = firebase.database().ref("wares/" + userId).child(waresID);
ref.once("value")
.then(function(snapshot) {
console.log(snapshot.val());
});
this will return only data related to that waresID or userId
Note: this is javascript code, i hope this will work for you.

login page not working (javascript, firebase)

HELP!
I'm not sure what's going on, but my login page isn't working. It simply reloads even though I'm entering valid user/password.
I think the problem is it's getting stuck on issues with my data-structure, security-rules, and app.js, but I'm at a loss.
I was provided a sinatra/ruby simple api to work with users & groups (just a small project).
here's the site:
https://starter-vicks9985.firebaseapp.com/index.html
here's the code:
$.post/("https://starter-vicks9985.firebaseapp.com/main.rb",
{
"name": "admin",
"email": "admin#example.com",
"password": "secret",
"admin": true,
"role-value": 99,
}
), console.log("success");
{
"rules": {
".read": true,
"users": {
"$user": {
//can add a message if authenticated
".write": "auth.uid === $user"
}
},
"rooms": {
"$room": {
"users": {
// can write to the users list only if ADMINISTRATOR
"$user": {
"write":"newData.parent().child(auth.uid).val() === 99"
}
}
}
},
"messages": {
"$room": {
"$message": {
//can add a message if they are a MEMBER (if there was message/chat capability)
".write": "(!data.exists() && newData.exists() && root.child('rooms/' + $room + '/users/' + auth.uid).val() >= 10)"
}
}
}
}
}
$(document).ready(function() {
/**
*Set initial firebase ref. Use set to write in first admin user.
*/
var ref = new Firebase("https://starter-vicks9985.firebaseio.com/");
ref.set({
"name": "Admin",
"email": "admin#example.com",
"password": "secret",
"admin": true
});
/** Get email address from loginform, format email, get password
* Firebase keys cannot have a period (.) in them, so this converts the emails to valid keys
*/
var emailAddress = function emailToKey(emailAddress){
return btoa(emailAddress);
};
var password = document.getElementById('password');
/**
* Authorize user with email and password, passing in values from form.
*/
ref.authWithPassword({
email : emailAddress,
password : password,
}, function(error, authData) {
if (error) {
console.log("Login Failed!", error);
} else {
return authData;
}
});
/**
* If user is logged in (valid), redirect to user profile
*/
ref.onAuth(function(authData) {
window.open="https://starter-vicks9985.firebaseio.com/userprofile/userprofile.html";
})
});

Like #Kato said, this is a code dump so please consider creating an mcve. Although, first check out my comments below.
The Code You Posted
After glancing at your code, I see some errors that I will point out:
1. Your jQuery post syntax is incorrect, and wouldn't work even if it was correct.
Most importantly, you are making a post request to a Ruby file. Firebase Hosting is not a server, it is hosting for static files.
See this answer by Frank. He says:
Firebase hosting is a product to serve so-called static application, which consist only of files that the client interprets. Firebase's servers will not interpret any code that you upload. So Firebase hosting is not suited to host your Ruby-on-Rails application.
To quote Firebase hosting's documentation:
We deliver all your static content (html, js, images, etc)
That being said, take a look at the jQuery documentation for $.post().
See my comments on your code:
$.post/("https://starter-vicks9985.firebaseapp.com/main.rb",
// ^ What is this '/'?
{
"name": "admin",
"email": "admin#example.com",
"password": "secret",
"admin": true,
"role-value": 99,
}
), console.log("success");
// ^ You are closing the function call, 'console.log' falls outside of it.
What it should look like:
$.post("https://starter-vicks9985.firebaseapp.com/main.rb", {
"name": "admin",
"email": "admin#example.com",
"password": "secret",
"admin": true,
"role-value": 99,
}, function() {
console.log("success");
});
2. What's even going on with the login functions?
Assuming you fix Uncaught SyntaxError: Unexpected token { in data-structure.js:14...
If you take a look at the console, you will see Uncaught Error: Firebase.authWithPassword failed: First argument must contain the key "email" with type "string".
That is because you are passing a function, emailAddress to .authWithPassword().
You declare emailAddress() like so:
var emailAddress = function emailToKey(emailAddress){
return btoa(emailAddress);
};
So the email parameter in the following is being passed emailAddress(), not a string that is an email address.
ref.authWithPassword({
email : emailAddress,
password : password,
}, function(error, authData) {
if (error) {
console.log("Login Failed!", error);
} else {
return authData;
}
});
Most importantly, all of these login functions are being called immediately after the page loads. Nothing in your code (app.js) waits for, and responds to, the submission of the form.
The Code on Your Website
I also went on your page, looked at your source code, and found some more issues.
1. Error in form HTML in index.html
<section class="loginform cf">
<form id= "login" form name="login" form type= "submit" accept-charset="utf-8">
<!-- extra^space ^duplicate "form"^ ^again, space -->
...
</form>
</section>
2. Syntax Errors in data-structures.js
Again, you have the same errors here as I described above ('/' and closing parentheses), but the object that you're passing the post is incorrectly formatted
$.post/("https://starter-vicks9985.firebaseapp.com/main.rb",
{
"users" //missing ':' after users
//the following objects do not have keys - should be {"users":{"someUserKey1":{...},"someUserKey2":{...}}} etc.
{
"name": "admin",
"email": "...",
"password": "...",
"admin": true,
"role-value": 99,
},
{
"name": "aaa",
...
},
{
"name": "bbb",
...
}
},
), console.log("success");
And the same things apply for the post call for "groups".
I hope that provides some clarity.
I would suggest reading over other answers here on StackOverflow, like:
jQuery AJAX submit form
jQuery form submit
And search for more answers like:
https://stackoverflow.com/search?q=jquery+form+submit
In conclusion, I'd suggest doing some more research and reading documentation :)
