Go to this file ...\site-packages\fbchat\_state.py Replace the following line FB_DTSG_REGEX = re.compile(r'name="fb_dtsg" value="(.*?)"') To this FB_DTSG_REGEX = re.compile(r'"fb_dtsg","value":"(.*?)"')

Despite the modification, nothing changes, I got the same error

For me, that fixed the error, but it created a new one.

Traceback (most recent call last):
  File "C:\Users\<user>\AppData\Local\Programs\Python\Python37\lib\site-packages\fbchat\_client.py", line 209, in login
    user_agent=user_agent,

    return cls.from_session(session=session)
  File "C:\Users\<user>\AppData\Local\Programs\Python\Python37\lib\site-packages\fbchat\_state.py", line 190, in from_session
    revision = int(r.text.split('"client_revision":', 1)[1].split(",", 1)[0])
IndexError: list index out of range

Maybe its because you are using an unsupported browser. I got the same error, so I added a custom user-agent. This fixed the error for me

from fbchat import Client

ua = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.111 Safari/537.36"
client = Client('<email>', '<password>', user_agent=ua)

Python\Python38-32\lib\site-packages\fbchat\_state.py", line 188, in from_session fb_dtsg = FB_DTSG_REGEX.search(r.text).group(1) AttributeError: 'NoneType' object has no attribute 'group'

Replace the following line FB_DTSG_REGEX = re.compile(r'name="fb_dtsg" value="(.*?)"') To this FB_DTSG_REGEX = re.compile(r'"fb_dtsg","value":"(.*?)"')
