Sidenote:
I don't want chapters. However, Emby forces chapter extraction if "Video Preview Thumbnails" is enabled. You can't have one without the other...
These are two different things.
In Jellyfin you can disable one or the other, or keep both enabled. For some reason, Emby doesn't allow that...

Upon clicking on a chapter #, a GET request is sent to `https://hostname/emby/Users/<user_id>/Items/chapter_XXXXXX_XXXXXXXXXXX`.

It fails with 500 - Internal Server Error

Hi there, please attach the complete emby server log file. Thanks.

I can reproduce the issue. I think the stack trace should be enough, right?
For context, the exception happens not when we click on the thumbnail for the chapter. That works just fine.
It happens when we click on the chapter name.

To be clear, the corresponding response that contains the request information is like this:

Hi, we’ll take a look at it. Thanks.
