TypeError: Cannot read properties of undefined (reading 'key')

[DeanSabbah]

Describe the bug When entering the Unassigned faces in the photos/people tab, the console logs this error. I am using the Recognize app for facial recognition.

To Reproduce Steps to reproduce the behavior: While using the Recgnize app

1. Go to Photos
2. Click on People, then unassigned faces
3. See error

Expected behavior I assume the pictures should load and I should be able to manually assign the faces

Additional Context After entering the unassigned faces tab, I can no longer change to any other tab within the Photos page (I can still switch to the files page).

I am receiving the same:

Also getting this. Seeming to find that unassigned faces are also not showing whatsoever, although I'm unsure whether this is a photos issue or a recognize issue.

[DeanSabbah]

I am almost certain that it is the photos app, as recognize works perfectly with the memories app.

Good spot - just tried this myself. 100% the photos app.

For additional context, it looks like it happens in VirtualScrolling.vue#updateScrollPosition when you reach the bottom of the preloaded content

I don't know if this is related, but if I click on an image in "Unassigned Faces" to preview it, I get another undefined error:

Edit: I see this was fixed in https://github.com/nextcloud/photos/pull/2468 but I don't have that change, so I think I just need to upgrade my version for that
