twitter-monitor\stream.py Syntax Error

[ybninputr]

i use django 2.2
i've followed through the instructions while making some changes to adjust the newest version. the admin page works.
however when i run python manage.py stream i get error

File "C:\Dev\Env\lib\site-packages\twitter_monitor\stream.py", line 117
    self.stream.filter(track=tracking_terms, async=True, languages=self.languages)
                                                 ^
SyntaxError: invalid syntax

the proble seems to be from the library and im not sure how to fix this since this is the first time i've tried django. do you have any idea what i could do to fix this?
