“” I just updated the regex like this and it’s working: ^\$*\w+\W “”

sorry had to edit - the image alone was not specific at all, note the change implemented on line 30 of cipher.py:

I have updated cipher.py as suggested and now I have a new error pytube.exceptions.RegexMatchError: regex_search: could not find match for (?:v=|\/)([0-9A-Za-z_-]{11}).*. This one comes from extract.py file. More specifically, this is the function throwing the error:

def video_id(url: str) -> str:
    return regex_search(r"(?:v=|\/)([0-9A-Za-z_-]{11}).*", url, group=1)

How can I go about it?

I have this simple code that causes this: https://dpaste.com/9M6KAUK28

I also had this issue. Amazing how active this thread is, and how many users there are. However, it looks like the project is difficult to maintain, and requires constant fixes…
