Have the same problem with a complete new installation from scratch. No addons activated so far. In the Photos-App the buttons work, in file viewer it is not working, also the Autoplay Button.
Tested with Firefox and Google-Chrome

Found out, that it is only not working if I'm logged in. If I share a public link of the folder, there it is working fine.

Same here, tested under Ubuntu 22.04 and lmde7, various browsers.

[jolang]

i can confirm this bug with Nextcloud 31.0.10.

[R053NR07]

Same Problem here on Nextcloud 31.0.10 but bug active since around 24.09.2025 so more versions should be affected.

Also the bug also disappears here when accessing the gallery through a public link.

I am experiencing the same issue with media scrolling directly in the browser.

Initially, I cleared the browser cache (Brave), but it did not resolve the problem. Then I tested on another computer using a different browser (Edge), and the issue persists.

On the server, I cleared the cache, applied all available updates, and restarted the system. Despite this, the problem continues on this version.

Same here with NC 32.0.1.
But I don't think, that this is a problem of the Photos app. I think this is a Problem in Nextcloud Viewer.

I encountered an issue in the Nextcloud Viewer where it fails to open some files. According to the browser console output, it seems that the Viewer is trying to access properties of a file that does not exist in the internal loaded file list, which results in a TypeError when reading filename or mime.

Console output:

TypeError: Cannot read properties of undefined vue.rintime.esm.js:3065
(reading 'mime')
at r. openFileFromList (Viewer.vue: 820:1)
at r.next (Viewer.vue:1087:1)

I plan to try regenerating thumbnails and updating the file index to see if the issue persists.

I did this already - no change. Nextcloud 32.0.1 as well here. My test environment with Nextcloud 32.0.0 works fine though.

And yes, it is not the Photos app but the viewer in the Files app - which is still available, even if the Photos app is disabled.

When will the update arrive on stable for 32.0.1? Since I did not get any update so far and it is still broken on my side on all 3 nextcloud ikstances.
