When i disconnect a client from the whatsapp app, puppeteer throws an error that damages any client i've created

Is there an existing issue for this?

Describe the bug

Well, like the title says, if i unlink the whatsapp client using my phone's whatsapp app, the expected behaviour is for the client to emit the disconnected event, just 1 client, the one that got disconnected, but instead, what happens is that i get a log like this on my console: uncaughtException: Protocol error (Network.getResponseBody): Session closed. Most likely the page has been closed.

Now, this exception damages any other client i may have open...

Meaning, if i use the localAuth strategy, and use multiple clients in my app, if only 1 of let's say, 10 clients disconnects from their phone, 10 clients are affected, because of the puppeteer exception that gets thrown.

I'm using manjaro os for testing, an arch linux distro btw.

Expected behavior

I guess just 1 client should get disconnected and every other one should work normally.

Steps to Reproduce the Bug or Issue

Use the localAuth strategy, and connect multiple clients.

Connect a client scanning the qr code.

Disconnect the client from the whatsapp mobile app.

An error gets thrown.

Now my webserver throws 500 internal server error on any occasion.

You can use the following code in your entry file, which will catch exceptions and will not cause your application to crash. `process.on('uncaughtException', (err) => {

})`

@a20000110 do you mean attaching an event handler to the Client object?

[luisdbarboza]

For additional info, i created a client with the localAuth strategy, i sent a message with the client, and after i closed the session from the whatsapp app, the library throws this error:

uncaughtException: Protocol error (Networ.getResponseBody): Session closed. Most likely the page has been closed at CDPSession.send (...restOfThePath/node_modules/puppeteer/lib/cjs/puppeteer/common/HTTPResponse.js:128:57

[luiscuriel]

How are you closing the app? You need to call client.destroy()

[luisdbarboza]

Hmm, yes, i'm destroying the client every time, but you see, even if i delete the .wwebjs_auth, or even if i don't do anything in the client.on('disconnected'. (callback)) event handler, it stills throws the error i described above

Same issue here. I tried to add a try catch in the entire Cliente intializing function but puppeteer error is still crashing the server. @a20000110 solution is a workaround for ANY not handled exception so be careful using it. The best solution is to handle the exception directly.

[luisdbarboza]

@a20000110 solution isn't working for me, because well, the app itself is not crashing completely, if i put an event handler for the uncaughtException i can log the error in the console, the process doesn't stop, but, i get the uncaughtException error logged in the console, and also my endpoints start sending responses with status 500 internal sever error

Same issue here: Protocol error (Runtime.callFunctionOn): Session closed. Most likely the page has been closed.

I've noticed that when Chromium is closed (can test in task manager), the event client.on('disconected'... is not fired And when try to send any message the error occurs: Error: Protocol error (Runtime.callFunctionOn): Session closed. Most likely the page has been closed.

Anyone facing this issue?

Work for me install independent "puppeteer": "^22.6.4". Try it.

Is this issue resolved? If I unlink my device from whatsapp mobile app, then i am not able to re-scan the QRs generated. Can someone please help. I am quite new to this.
