This is my first time using Nextcloud for more than some testing and I just installed the latest version not much thinking about it. And it seems like version 33 has some kinks to work out.
My issue is mentioned in 500 error: WebP exif parsing fails due to bad composer autoload · Issue #3425 · nextcloud/photos · GitHub , but I’m not versed enough in how Nextcloud works yet. So I’m not able to figure out a temporary solution.
I would appreciate some help / guidance, so I can fix this locally, since it doesn’t seem like there is anybody working on this yet. At least nobody mentioned that in the Github issue.
The Basics
- Nextcloud Server version (e.g., 29.x.x):
33.0.0
- Operating system and version (e.g., Ubuntu 24.04):
- Linux 6.12.33-production+truenas x86_64
- Web server and version (e.g, Apache 2.4.25):
nginx/1.29.6
- Reverse proxy and version _(e.g. nginx 1.27.2)
nginx-proxy-manager 1.3.3 (not relevant)
- PHP version (e.g, 8.3):
8.4.18
- Is this the first time you’ve seen this error? (Yes / No):
No
- When did this problem seem to first start?
Every time you upload a web
- Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
Docker (TrueNas package)
- Are you using CloudfIare, mod_security, or similar? (Yes / No)
Yes
Summary of the issue you are facing:
I have a library with some webp images, and every time I upload another one I’m getting this error - but no data is lost despite it saying the files can’t be synced. But the error’s are pretty annoying.
Steps to replicate it (hint: details matter!):
-
Upload an webp image
-
Get an error in the webui or desktop client that the upload failed, because of a server error (but upload is there)
