Can only see folders, not bookmarks

[BenLangers]

The app is no longer showing bookmarks. I see the folders. The folder tree on the left is showing the amount of bookmarks that should be there. The folder view shows only other folders, not the bookmarks. If there are no folders, it shows "No bookmarks here".
I found a comparable issue where it was mentioned that mysql had to be upgraded to version 8, but my installation is using Postgres (just upgraded from 16 to 17, but this does not seem to have any effect).

To Reproduce
Open any folder in the bookmarks app.

Additional context
Not sure how long it has been broken, noticed when trying to set up sync with a new client.

Bit uncomfortable to post full logs. From the container images, everything is aggregated and contains too much sensitive information to try and sanitize it. If there is any reference what we would be looking for, happy to dig in. I did not see any obvious error message (in general, or from the bookmarks app specifically)

Hello 👋

Thank you for taking the time to open this issue with the bookmarks app. I know it's frustrating when software
causes problems. You have made the right choice to come here and open an issue to make sure your problem gets looked at
and if possible solved.
I'm Marcel and have been maintaining this software the last few years. I currently work for Nextcloud but maintain this app
in my free time, because it is not an official Nextcloud product. My day job at Nextcloud is pretty awesome but sadly leaves me with
less time for side projects like this one than I used to have.
I still try to answer all issues and if possible fix all bugs here, but it sometimes takes a while until I get to it.
Until then, please be patient.
Note also that GitHub is a place where people meet to make software better together. Nobody here is under any obligation
to help you, solve your problems or deliver on any expectations or demands you may have, but if enough people come together we can
collaborate to make this software better. For everyone.
Thus, if you can, you could also look at other issues to see whether you can help other people with your knowledge
and experience. If you have coding experience it would also be awesome if you could step up to dive into the code and
try to fix the odd bug yourself. Everyone will be thankful for extra helping hands!
One last word: If you feel, at any point, like you need to vent, this is not the place for it; you can go to the forum,
to twitter or somewhere else. But this is a technical issue tracker, so please make sure to
focus on the tech and keep your opinions to yourself. (Also see our Code of Conduct. Really.)

I look forward to working with you on this issue
Cheers 💙

Hello @BenLangers
thank you for taking the time to give feedback by opening this issue!
Are you certain that you are on version 16.2.1 and not on 16.2.2 which was released today?

[marcelklehr]

A good first measure is, if you have floccus set up, to stop auto-sync there, to avoid syncing down that server state. Although, floccus should have a failsafe.

[BenLangers]

Hi! Wow, now that is fast :)

Yes, just checked. I upgraded earlier this week to see if this would fix the issue, was still 16.2.1 at the time.
I do use floccus to work with my bookmarks locally, indeed. This is currently not working with a 'server error 500'. It should not be actively syncing anywhere currently.

Thank you for the very fast response!

[marcelklehr]

Do you have a backup of your database? If so, I think we should try to update to v16.2.2 as that fixes quite some issues.

[marcelklehr]

Also, that error 500 might be in your nextcloud logs with a more useful error message. Could you dig that up?

[BenLangers]

I will have copies of my bookmarks synced to various devices up to the point the issue started, that should do as a backup should anything get destroyed beyond repair.
I did not see anything relevant pass by in the Nextcloud logs earlier, but will check again after I upgraded the app to 16.2.2. Get back to you asap!

[BenLangers]

Issue stays the same on 16.2.2.
When browsing through the app, nothing relevant seems to show in the Nextcloud logs. This is what was logged when opening several folders and refreshing the page:

I do not see any logs with a context of 'bookmarks' or such.

The container logs during this looked like this:

Looks like GET /apps/bookmarks/bookmark is returning 500, but there are not web server error logs at that time (should be logged to stdout just as well).

Can you check the nextcloud.log file? It's in your nextcloud data directory: usually that is nextcloud/data/nextcloud.log

[marcelklehr]

Different angle: Could you check the response payload from the server that is sent with the 500 response? In some cases the bookmarks app send the 500 on it's own.

[BenLangers]

I only seem to find those deprecation warnings in de log file.
How do I check that response? Can I see that in the browser developer tools? 'll try and find those asap.

[marcelklehr]

Can I see that in the browser developer tools?

Yes, developer tools -> Network

[marcelklehr]

The response may not contain much information, though. If you have access the following changes in the app code can reveal what's the issue: https://github.com/nextcloud/bookmarks/pull/2464/changes
-- this will log an error in the nextcloud whenever the bookmark endpoint is returning http 500

[marcelklehr]

@BenLangers Any update?
