I can reproduce this error on v2.0.0a5 when logging in via username/password.

Logging in via saved session also seems to fail, with the message below and a massive wall of HTML.

 fbchat.ParseError: Could not find enough ServerJSDefine. Please report this, along with the data below!

[AstroCB]

Looks like the exception is being raised here, indicating that there's a missing Location header in the response. Seems like Facebook may have changed the redirection logic and no longer redirects after a successful login via a POST to that route.

As for the session issue, exception is being raised here, so the HTML dump I mentioned above isn't being parsed properly (there is only one define_split?). Not sure if this change is related to the email/password failure or separate.

Edit: I'm pretty sure they're related, since the content of the response to the POST that is no longer redirecting looks very similar to the HTML dump given by the session error.

@madsmtm any idea how to fix this?

No progress on this issue?

Okay, this works from fbchat.readthedocs.io.

from fbchat import Client
from fbchat.models import *

client = Client("<email>", "<password>")
client.send(Message(text="Hi me!"), thread_id=client.uid, thread_type=ThreadType.USER)

client.logout()

But facebook blocked my account after 3 days. I didn't send any message through the bot.
