[BE]Some videos cannot be downloaded.

[MotiCAT]

Details

Some of the so-called "topic," or background music-only videos, can be downloaded, while others cannot.
An example

ツッパリくんvs 関取マン

スラサタンナ幻想曲

The error encountered when trying to perform the download is an Internal Server Error (error code 500).

Cause

The only thing these videos have in common is that they are "topic" videos, and their other relevance is unknown.

Dear @MotiCAT
Thanks for the bug report.
As for this issue, I could not reproduce it locally, so it seems to have occurred after deploying to Vercel.
I have created a dedicated branch and will try to debug it there.

We checked the error response and found the following results

{"error":{"info":{"error_type": "UNPLAYABLE"}, "date": "2023-09-25T14:05:40.715Z", "version": "6.4.0"}}

I found a related Issue on Youtubei.js.
I would like to find out more about the cause.

I have checked and retried the above Issue but can't seem to resolve it...
I will try to find some more information.

@MotiCAT
The cause was found.
The error seemed to be due to the video being inaccessible from the region of Vercel's server.
We will modify the error modal to emit an error modal once we have an alternative solution.
The branch for this Issue will be deleted once.

Alternatives

• use proxy
• Change the server location.

We have tentatively addressed the above to generate an error modal.
We will respond as soon as we find another solution other than deploying servers in multiple regions.
