Firebase: Cloud function changing data in firestore - Permission denied on resource project [X:YYYYYYYYYY:web:KKKKKKKKKKKK]

I am trying to add data to my firestore collection via firebase cloud functions. However, when executing the function the following error appears.
My cloud function code is:
import * as functions from "firebase-functions";
import * as admin from "firebase-admin";
admin.initializeApp();
const Firestore = require("#google-cloud/firestore");
const PROJECTID = "[...]";
const firestore = new Firestore({
projectId: PROJECTID,
timestampsInSnapshots: true,
});
exports.createNewChat = functions.region("europe-west1")
.https.onRequest((request, response) => {
console.log("!!!!!!");
console.log("THe BodY: " + request);
console.log("THe BodY: " + request.rawBody);
console.log("THe BodY: " + request.body);
try {
const groupName = request.body.groupName;
const members: string[] = request.body.members;
firestore.collection("chats").add({
groupName: groupName,
members: members,
lastMessage: new Date(),
messages: [],
}).then((doc: any) => {
const chatId = doc.id;
members.forEach((member) => {
firestore.collection("myChats/" + member).add({
chatKey: chatId,
});
});
return response.status(200).send(doc);
});
} catch (e) {
functions.logger.log("catch clause " + e);
response.status(500).send(e);
}
});
My postman request looks like this:
Header: Content-Type -> application/json
Body (raw, json):
{
"groupName": "someGroupName",
"members": [
"123321aklslasl"
]
}
The exception which is thrown is:
! Google API requested!
URL: "https://oauth2.googleapis.com/token"
Be careful, this may be a production service.

In a Cloud Function for Firebase you should use the Admin SDK for Node.js and not the standard JS SDK.
In addition, you need to use Promise.all() to execute in parallel the calls to the asynchronous add() method in the forEach() loop.
So the following set of adaptations should solve your problem:
import * as functions from "firebase-functions";
import * as admin from "firebase-admin";
admin.initializeApp();
exports.createNewChat = functions.region("europe-west1")
.https.onRequest((request, response) => {
const groupName = request.body.groupName;
const members: string[] = request.body.members;
const db = admin.firestore();
db.collection("chats").add({
groupName: groupName,
members: members,
lastMessage: new Date(),
messages: [],
}).then((doc: any) => {
const chatId = doc.id;
const promises = [];
members.forEach((member) => {
promises.push(db.collection("myChats/" + member).add({
chatKey: chatId,
}));
});
return Promise.all(promises);
})
.then(() => {
response.status(200).send(JSON.stringify(doc));
})
.catch(e => {
functions.logger.log("catch clause " + e);
response.status(500).send(JSON.stringify(e));
});
});

Since when I started using discord.js V12 i walk with many doubts and one of them is, how to catch the avatar of a user? Can someone help me? I know it's a stupid doubt but I really don't know

message.author.avatar is not a method. You need message.author.avatarURL
//author's avatar:
.setThumbnail(message.author.avatarURL);
As mentioned above, try using the docs

// In discord.js v12
message.author.displayAvatarURL()

I was having a similar issue. The problem was that Discord was being sent the embed before the promise of fetching the user and image was fulfilled. This is the code I used to get this functionality.
const client = new Discord.Client();
let thanos = client.users.fetch('IDHERE');
thanos.then(function(result1) {
//put your code that uses the result1 (the user object) here
//for example, you could put your entire embed in here and
//in setFooter you could use result1.displayAvatarURL()
});

Discord bot wont run seemingly correct code

So I'm writing an unban script for my discord bot - it keeps throwing errors when ONLY this command is used - it looks correct to me and my mate, is there something I am overlooking?
const discord = require("discord.js");
module.exports = {
name: 'unban',
category: 'moderation',
description: 'unban a members',
aliases: [''],
run: async (message, client, args) => {
let unbanned = message.mentions.users.first() || client.users.resolve(args[0]);
let reason = args.slice(1).join(" ");
let member = await client.users.fetch(unbanned);
let ban = await message.guild.fetchBans();
// MESSAGES
if (!unbanned) {
let unbaninfoembed = new Discord.MessageEmbed()
.setTitle("Command: unban")
.setDescription(
`**Description:** Unban a user. \n` +
"**Sub Commands:**\n" +
"" +
"**Usage:**\n" +
"-unban [user] (limit) (reason) \n" +
"**Examples:** \n" +
"-unban <#759175803409530932> good guy \n" +
"-unban 759175803409530932 good guy "
)
.setColor("#2C2F33");
message.channel.send(unbaninfoembed);
return;
}
if (!ban.get(member.id)) {
let notbannedembed = new Discord.MessageEmbed()
.setDescription("This user is not banned")
.setColor("#2C2F33");
message.channel.send(notbannedembed);
return;
}
if (!message.guild.me.permissions.has("BAN_MEMBERS")) {
let botnoperms = new Discord.MessageEmbed()
.setDescription(
"I do not have permissions, please contact an administrator"
)
.setColor("#2C2F33");
message.channel.send(botnoperms);
return;
}
if (!message.member.permission.has("BAN_MEMBERS")) {
let nopermsembed = new Discord.MessageEmbed()
.setDescription(
"You do not have permission `BAN MEMBERS` contact an administrator"
)
.setColor("#2C2F33");
message.channel.send(nopermsembed);
return;
}
var user = ban.get(member.id);
message.guild.members.unban(member);
let successfullyembed = new Discord.MessageEmbed()
.setTitle(`Successfully Unbaned!`)
.setDescription(`${member.tag} has been successfully unbanned`)
.addField(`Reason: ${reason}`)
.setColor("#2C2F33");
message.channel.send(successfullyembed);
},
};
Gives the error:

Recently Discord has changed the main website from "discordapp.com" to "discord.com", try reinstalling the discord.js module and see if it helps.

Discord.js embed image not working. (Could not interpret "{'url': 'https://cdn.nekos.life/boobs/boobs105.gif'}" as string.)

My command.js
based on some other bots like HarutoHiroki Bot thst open source on Github and the Nekos.life documentation
const Discord = require('discord.js');
const client = require('nekos.life');
const neko = new client();
module.exports.run = async (bot, message, args) => {
if (message.channel.nsfw === true) {
link = await neko.nsfw.boobs()
console.log(link)
const embed = new Discord.MessageEmbed()
.setAuthor(`Some neko boobs`)
.setColor('#00FFF3')
.setImage(link)
.setFooter(`Bot by`);
message.channel.send(embed);
}
else {
message.channel.send("This isn't NSFW channel!")
}
};
module.exports.config = {
name: "boobs",
description: "",
usage: "*boobs",
accessableby: "Members",
aliases: []
}

My Question
how to fix this? (I tried the hole day but didn't got it working need help soon as possible)

I fixed it:
const Discord = require('discord.js');
const client = require('nekos.life');
const neko = new client();
module.exports.run = async (bot, message, args) => {
if (message.channel.nsfw === true) {
link = await neko.nsfw.boobs()
const embed = new Discord.MessageEmbed()
.setAuthor(`Some neko boobs`)
.setColor('#00FFF3')
.setImage(link.url)
.setFooter(`Bot by`);
message.channel.send(embed);
}
else {
message.channel.send("This isn't NSFW channel!")
}
};
module.exports.config = {
name: "boobs",
description: "",
usage: "*boobs",
accessableby: "Members",
aliases: []
}

It looks like neko.nsfw.boobs() returns an object, not a string. Try this instead:
const { url } = await neko.nsfw.boobs(); // get only the URL, not the whole object
const embed = new Discord.MessageEmbed()
.setAuthor(`Some neko boobs`)
.setColor('#00FFF3')
.setImage(link.url)
.setFooter(`Bot by`);
message.channel.send(embed);
Here's a code snippet example:
const link = {
url: 'https://cdn.nekos.life/boobs/boobs105.gif'
};
console.log(link); // this will not give the link. it will give the whole object
/* using object destructuring, you can use brackets to capture one
property of an array. in this case, the url.
Object Destructuring - https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Operators/Destructuring_assignment
*/
const {
url
} = link;
console.log(url); // this will give *only* the link
console.log(link.url); // another method to give only the link

Web-scraping images with JavaScript Cheerio

I receive an error when attempting to web-scrape images off amazon. The goal is to download the book cover.

Here is my code thus far. I believe my error stems from the line;
var imagesrc = $(".a-row center-align litb-on-click img").attr('src')
I need to access the Class over where the book url is, though i might be wrong.
const express = require('express');
const cheerio = require('cheerio');
const download = require('node-image-downloader');
const request = require('request');
const app = express();
app.get('/', (req, res) => {
var url = "https://www.amazon.com/Black-Swan-Improbable-Robustness-Fragility/dp/081297381X"
// makeing a request
request(url,(error, response,html) => {
if (!error){
//console.log(html);
var $ = cheerio.load(html)
var imagesrc = $(".a-row center-align litb-on-click img").attr('src')
//download the image
download({
imgs: [
{
uri:imagesrc
}
],
dest:'./downloads'
})
.then((info) => {
console.log("Download Complete")
process.exit(1)
})
}
})
})
app.listen(5000)

Here, a-row center-align litb-on-click are classes
To select a class we need to use class-selector . (dot)
please try to update your imagesrc variable as below
var imagesrc = $(".a-row.center-align.litb-on-click img").attr('src');
