AttributeError: module 'headers' has no attribute 'token'

I've got this after manually entering the PSSH (I don't need other site support, I think). Here's how it appeared:

Here's the whole output off the PowerShell, if you need: NOTE: MPD and license URLs, PSSH has been replaced with hidden , I pasted the correct ones

PS C:\Users\USER\OneDrive\Desktop\widevine_keys-main>  & 'C:\Users\USER\AppData\Local\Microsoft\WindowsApps\python.exe' 'c:\Program Files\VS Code Extensions\ms-python.python-2021.9.1200949236\pythonFiles\lib\python\debugpy\launcher' '51391' '--' 'c:\Users\USER\OneDrive\Desktop\widevine_keys-main\l3.py' 

Input MPD URL: _hidden_
License URL: _hidden_
Unable to find PSSH in mpd. Edit getPSSH.py or enter PSSH manually: _hidden_

PSSH obtained.
