To Reproduce

1. Add a music library
2. Add a music video library
3. Edit the music videos to add an artist and album present in the music library (Or use an NFO)

Expected behavior

The "Music Videos" section on the artist and album page should be filled in with the relevant items. It is currently appearing, but is empty.

The AlbumArtistIds is correct for both the music video and the albums.

Additional context

[daullmer]

For the artists page, sending the artist id as parameter ArtistId instead of AlbumArtistId works fine.
The header is most likely displayed because the artist BaseItem has the property MusicVideoCount: 1.

The endpoint which gets called by the album page does return the correct data but doesn't display it.

is the album request which returns data for me

Can confirm this doesn't work for me either in 10.7.1. Video with one Artist set, Artist data has MusicVideoCount: 1, "Music Video" header is display but no items.

Music video list is displayed correctly for the director linked to videos.
