Server error logs

No response

Additional information

Could not find any log files on android so I obtained these logs via adb logcat
Every other folder on the server works without any problems

The text was updated successfully, but these errors were encountered:

#11982

jdaviescoates · 2023-11-07T10:12:08Z

I also have this issue, but for me it is randomly just one of the folders inside my InstantUpload folder that isn't working. Everything else seems fine.

kirmaha · 2023-11-27T15:16:35Z

Same here than OP, on /e/OS (murena). Solved by downgrading to 3.25.

Darklesss · 2023-11-28T01:01:58Z

Same for me on a Pixel 5a running CalyxOS. Will try downgrading to 3.25.

If it helps troubleshoot, when I click Activities in the hamburger menu I can still see my recent changes, and can (sometimes) retrieve the file I'm looking for. So the app is connected to the server, just not showing it in the main folder view.

Seems to be caused by the above crash. Possibly fixed in v3.27.0 by nextcloud/android-library#1242 (and, potentially by running the latest 27.1.x server-side since the metadata has been adjusted a bit).

chandlben · 2024-01-05T16:44:39Z

This problem just showed up on my Pixel 6a device with version 3.27 where only certain folders gave this error. I have a OnePlus 7 Pro that doesn't have the same issue it would seem. Tried to recreate with both 3.26 and 3.27 on the OnePlus and couldn't get the problem to surface. Downgrading to 3.25 on the Pixel fixed the issue. Server side I'm on 28.0.1.

Dare I say it's Pixel related?

panachoi · 2024-01-15T11:42:52Z

I'm having the same issue(s) with the exact same output in the logcat above. And indeed, it only affects certain folders. However, I can use another account without issue. Version 3.25 just works.

Experiencing the same issues on 3.27.0 on Android 14, but with a different log output:

The issue does occur on iOS/iPadOS.

Reverting back to 3.26.0 from F-Droid fixes the issue.

joshtrichards · 2024-02-26T21:22:34Z

In hindsight, this seems to be the same as #12379 (which is good because we know what is causing that).

joshtrichards · 2024-07-05T21:08:07Z

Fixed in nextcloud/android-library#1349
