To Reproduce Steps to reproduce the behavior:

  1. Go to '...' Photos in nextcloud
  2. Click on '....' Any Album or just the overview

Expected behavior Preview images to show

Linux Server Apache / nginx php8.3 / [Nextcloud Hub 9] (30.0.1) Image The URL to the preview not found images would be

/index.php/apps/photos/api/v1/preview/

Same issue here but the 404s are SEARCH calls to /remote.php/dav/

As a workaround, navigating to my photo directory in "/apps/photos/folders" instead of "/apps/photos/photos" seems to display previews fine.

(Linux, Apache, PHP 8.2.24, Nextcloud 30.0.1, Photos 3.0.2)

In that case previews on photos an folders are displayed for a very short time until there is a 404 in XHR requests from core, then Images vanish alongside with javascript errors. Image Image

So finally I tested something, I created a new NC instance on a subdomain, everything worked Then I connected Database and Data Directory of the not working Instance and ....... (listen to the drums) All was Broken again :-D So I guess it is NC Upgrade data shit migration what causes the trouble. It happened when I upgraded recently from 27 to 28,29,30

That upgrade path is what I did to get here as well. Could you please reopen the issue, I'm hoping for a fix that doesn't involve creating a whole new instance.

sure, but actually it is a data migration problem what might or might not be in the core or whereever upgrade process

Had the same issue with repeating 404 calls to remote.php/dav/ seemingly after upgrading from 28.0.10 to 29.0.8. Turned out that the config of the photos app was configured to use the default "Photos" as a media folder which was not present in the filesystem. Fixed by setting the correct media folder.

Do you have any path to the config of the photos app and/or the "Photos" dir in the filesystem? I put P/photos in the data dir where the users data lives with no effect.

Oh, hey! That fixed it for me. Thank you so much, @jkahrs! @sambibot, I just clicked "Photo settings" in the bottom left of /apps/photos/ and under "Media folder" added the correct folder. That must have changed during the upgrade.

sambibot commented 3 weeks ago

nope, that did not solve it for me, the setting was right, the folder existed, I chose another folder with pics in it, deleted the other and still /index.php/apps/photos/api/v1/preview/768?etag=8dee73c4145ef303badb0cc1291f12c9&x=64&y=64 404, it returns an empty json []

Also I found this: Error index Exception: OCA\Photos\Album\AlbumFile::__construct(): Argument #2 ($name) must be of type string, null given, 2024-11-01T11:00:30+00:00

My guess it is a mess in the filechach table
