Error while merging music albums not properly caught/displayed to the end user

[sn0opy]

Describe The Bug

I tried to merge 2 music albums which were split for some reason. While doing so, the servfer returned an error which was only displayed to the browser's dev console. The loading spinner is still being displayed.

Steps To Reproduce

1. Go to a music library
2. Select two albums
3. Clik the "Group versions" menu item
4. See an endless loading spinner

Expected Behavior

The server returned the following error message "Please supply at least two videos to merge.". I was expecting this error message to be displayed to me as some sort of modal in the front-end

Logs

https://<server>/Videos/MergeVersions?Ids=<id1>,<id2> returned an HTTP 400 Bad Request with the response message: "Please supply at least two videos to merge."

System (please complete the following information):

• Platform: Linux
• Browser: Chrome
• Jellyfin Version: 10.9.1

Additional Context

I assume this error should not have happened in the first place so I guess I should probably file another bug report in the server repo. Or is this feature only available to video files? Then this menu items should not be available anyway.
