RegexMatchError: get_throttling_function_name: could not find match for multiple v=15.0.0

I cannot use the video download feature via pytube

The code I ran yesterday is not working today. How can I fix the error for pytube 15.0.0?

def video_indir(video_url, dosya_adi):
    video = pytube.YouTube(video_url)
    audio_stream = video.streams.filter(only_audio=True).first()
    audio_dosya = f'{dosya_adi}.mp4'
    audio_stream.download(filename=audio_dosya)
    return audio_dosya

The error I got is here, the solution is elsewhere."

In Pytube version 15.0.0, you just need to remove ; in line 287 of cipher.py file.

Change r'var {nfunc}\s*=\s*(\[.+?\];)'.format( to r'var {nfunc}\s*=\s*(\[.+?\])'.format( " but I didn't understand it

Change the function_patterns array in cipher.py at line 264 to include this one and it seems to work:

function_patterns = [
    # https://github.com/ytdl-org/youtube-dl/issues/29326#issuecomment-865985377
    # https://github.com/yt-dlp/yt-dlp/commit/48416bc4a8f1d5ff07d5977659cb8ece7640dcd8
    # var Bpa = [iha];
    # ...
    # a.C && (b = a.get("n")) && (b = Bpa[0](b), a.set("n", b),
    # Bpa.length || iha("")) }};
    # In the above case, `iha` is the relevant function name
    r'a\.[a-zA-Z]\s*&&\s*\([a-z]\s*=\s*a\.get\("n"\)\)\s*&&.*?\|\|\s*([a-z]+)',
    r'\([a-z]\s*=\s*([a-zA-Z0-9$]+)(\[\d+\])?\([a-z]\)',
    r'\([a-z]\s*=\s*([a-zA-Z0-9$]+)(\[\d+\])\([a-z]\)',
]
