Describe the bug

I am trying to make a chatbot with automatic responses, sometimes the sendMessage is not working. There is no error but the message is not sending. If i execute in non-headless mode i see the red icon that says that there was an error.

as you can see in the image it was working and then start to show the error.

Expected behavior

Send a message after the user writes a specific word.

Steps to Reproduce the Bug or Issue

1. Connect with qr with LocalAuth strategy.
2. Some send a message.
3. The bot should respond to the user
4. The message is not sending.

Relevant Code

const { Client, LocalAuth, List } = require('whatsapp-web.js'); const qrcode = require('qrcode-terminal');

const client = new Client({ authStrategy: new LocalAuth(), puppeteer: { headless: false } });

const lastMessages = new Map();

client.on('qr', qr => { qrcode.generate(qr, { small: true }); });

client.on('ready', () => { console.log('Dispositivo conectado'); });

client.on('message', message => { //console.log('message: ', message); if(message.body.trim() === 'test_bot') { client.sendMessage(message.from, 'Some text'); } });

Don't send buttons or lists.

They don't work and break the web. Upgrade your connection and everything will work.

As you can see in the code the message is just plain text

I am facing the same issue. Sometimes the message is not sent out even though there is no error.

[templar-ajay]

same here, the sendMessage method returns success result but the message is not sent

[matbks]

Here it wont even "fake send". it just wont reply neither sendMessage, 0 errors also.

edit:

Solved my problem:

npm i github:pedroslopez/whatsapp-web.js#9a6466edbc4af5b5eeea060917c15f86b283f510

found this answer in #2473

[Redskinsjo]

i resolved it by correcting my own code: in my cas the for loop was incorrectly set, and so it was releasing an infinite loop and preventing the code to be executed smoothly
