Unable to use youtube-dl or annie to download video from Bilibili

So I was trying to download a video from Bilibili using annie. I oroginally chose youtube-dl but unfortunately it doesn't seem to support Bilibili website, so I chose annie instead, following the advice from a reddit user But despite it seems I have no luck using Annie either. I wonder if this is because Bilibili has updated their mechanism or if I made a mistake somewhere. This is the code.

apple@apples-MacBook-Pro ~ % annie "" Downloading error: this page has no playlist apple@apples-MacBook-Pro ~ % 

Also, youtube-dl claims it supports Bilibili and I definitely remember downlowding video from Bilibili using youtube-dl not so long ago. So what happened. Did Bilibili update their code or something?

apple@apples-MacBook-Pro ~ % youtube-dl "" [BiliBili] 90163846: Downloading webpage [BiliBili] 90163846: Downloading video info page WARNING: Unable to download JSON metadata: HTTP Error 412: Precondition Failed [BiliBili] 90163846: Downloading video info page ERROR: Unable to download JSON metadata: HTTP Error 412: Precondition Failed (caused by HTTPError()); please report this issue on . Make sure you are using the latest version; type youtube-dl -U to update. Be sure to call youtube-dl with the -- verbose flag and include its complete output. apple@apples-MacBook-Pro ~ % 

edit: Here is the debug log if it is of any help.

2 things you need to do to fix this:

1. Upgrade to the current version of youtube-dl. The Bilibili extractor was last changed on 8/March/2021 and when I tested with an older version, it didn't work
2. Use Bilibili URLs that look like as the input for youtube-dl. Don't use Bilibili URLs like the first example that has a /s/ in it. So instead of , you should use

add the following in the command

--add-header Accept:'/'
