    Probably a duplicate of [this Q&A](https://stackoverflow.com/q/68945080/5320906) – snakecharmerb May 08 '22 at 11:20
  • This is a [bug in pytube](https://github.com/pytube/pytube/issues/1311). A [fix](https://github.com/pytube/pytube/pull/1312/files) has already been developed but not published yet. Just edit `site-package/pytube/cypher.py` manually – Tranbi May 08 '22 at 11:30
  • And what is this: function_patterns = [ r'a\.[A-Z]&&\(b=a\.get\("n"\)\)&&\(b=([^(]+)\(b\)', ] – Jack Alvin May 08 '22 at 12:49
