I don't know anything about fbchat, but it looks like
FB_DTSG_REGEX.search is returning None (indicating that the search
failed), which doesn't have an attribute named "group."

I would suggest breaking up fb_dtsg =
FB_DTSG_REGEX.search(r.text).group(1) into multiple statements and
testing the result of the search before assuming that there's a group
attribute:

    xxx = FB_DTSG_REGEX.search(r.text)
    if xxx:
        fb_dtsg = xxx.group(1)
    else:
        print("the search failed, now what?")
