@lenslol Have you been locked out from logging into your Facebook account? Facebook seems to have gotten a lot more aggressive at blocking these types of scripts, sadly.

Nope. I was able to log back in afterwards. Its unfortunate, I think this feature is something sorely needed from messenger. Maybe they're worried of all the costs it will incur all at once. But I really need to grab an archive of all the media (500+) pictures in a specific chat. And your method is the only way I found.

Btw, I just found that there is also a macos/windows marketplace desktop version of Messenger. It's a LOT easier to scroll through the pictures there than it is on the web (as in they load a lot faster) I don't have the skillset to delve into it but if you do I'd recommend checking out whats going on in there, perhaps focus a script on that instead.

@lenslol did you ever get this to work?

@lenslol @outpoints I looked into it a little; someone suggested setting a valid user_agent value when logging in (which I tried), but it yields a new error.

It also seems like the Python package this script primarily relies on to interface with Facebook's backend is no longer maintained sadly: https://github.com/fbchat-dev/fbchat/issues/613

If the fbchat-dev/fbchat project gets updated, I'll give it another shot.
