invalid children order: A child is missing: bookmark:2325

[thd6n75]

Describe the bug
When syncing with Nextcloud, floccus fails with the message:

Nextcloud API error: {"status":"error","data":"invalid children order: A child is missing: bookmark:2325"}

Similar to #705 . When this happens, Floccus consumes a lot of CPU.

To Reproduce

1. Sync

Expected behavior

Successful sync

Screenshots
If applicable, add screenshots to help explain your problem.

Desktop (please complete the following information):

• OS: Ubuntu 18.04
• Browser Chromium
• Browser Version Version 89.0.4385.0 (Developer Build) Ubuntu 18.04 (64-bit)
• Floccus version: 4.4.8 (released yesterday, but I think the problem pre-dates this)
• Floccus sync method: nextcloud folders

Server (please complete the following information):

• OS: Ubuntu 18.04
• Nextcloud version: 20.0.3
• Bookmarks app version: 4.0.6 (problem initially occurred I think on 4.0.4 before I updated to 4.0.6)

Note: Please write down the actual version numbers instead of writing 'latest'.

Debug log
It is often useful to provide a debug log file along with the issue. You can obtain a debug log of the most recent sync runs by clicking 'Debug log' in the bottom right corner of the floccus panel in your browser.

Note: As your debug log usually contains large parts of your bookmark data, instead of attaching it publicly to the issue here, I recommend uploading it privately at the following URL https://klehranlage.net/index.php/s/7nn82NSBsfQKdsJ

Additional context

This didn't fix the issue:

docker exec --user www-data nextcloud php occ maintenance:repair

output:

     - Removed 0 duplicate shares
 - Remove superfluous shared bookmark folders
     - Removed 0 superfluous shares
 - Remove orphaned bookmark shares

A "sync from scratch" seems to temporarily fix this, but a couple syncs later the problem occurs again persistently.

Same problem occurred to me today.

It was fixed in my case by updating:
Floccus version: 4.4.8 -> 4.4.9
Bookmarks app version: 4.0.6 -> 4.0.8

I updated:

Floccus version: 4.4.9
Bookmarks app version: 4.0.8

And I still get this error after a sync from scratch.

Can you try again with the latest version?

I've been running 4.4.10 for a day and it seems to have fixed the issue. Thanks!
