Original GitHub issue: https://github.com/floccusaddon/floccus/issues/878

Describe the bug

I'm running Firefox 89.0b12 and Nextcloud 20.0.6. Whenever I try to sync my bookmarks using Floccus I get the error message "Failed to map parentId: 55".

To Reproduce

Steps to reproduce the behavior:

Click on the addon icon in Firefox's toolbar.
Click on 'Sync Now'

Expected behavior

I expected my bookmarks to be synced.

Screenshots

If applicable, add screenshots to help explain your problem.

Desktop

(please complete the following information)

OS: macOS Catalina
Browser Firefox
Browser Version 89.0b12
Floccus version: 4.6.4
Floccus sync method: (don't know where to get this information, just entered my Nextcloud login details in the Floccus settings)

Server

(please complete the following information)

OS: CentOS I think, my Nextcloud is hosted on a webspace
Nextcloud version: 20.0.6
Bookmarks app version: 4.2.0

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://cloud.marcelklehr.de/s/PCi3iLWrzdMZSmw

Debug log provided

Additional context

Add any other context about the problem here.

Thanks in advance for the help.

Same problem here, but with different parentID
"Failed to map parentId: 1282"
I can´t provide a debug log, because the Debug-Button doesn´t work.
I´m syncing to my NAS via Webdav. Last successful sync was on 16.05.21. I´m using Vivaldi 3.9.2289.3 on Win10

I didn't found the xbel.lock-file on my NAS.
Then I've deleted the xbel file on my NAS and made a new sync and anything works fine.

Maybe this helps you.
Sorry for the bad codelayout. The linefeed did not work for me in the codebox.

I landed here Googling the same issue. Just tried to sync with a browser I haven't synced with in a year.

@bernd-wechner what is your:

browser and its version
floccus addon version
nextcloud version
bookmarks app version

Have you tried latest versions if they fix the problem for you?

Works fine on Chrome at work.
Working at home and tried Chrome (as I has some Firefox issues with Outlook and was looking for a comparison).
Noticed bookmarks all old.
Synced, and got that error.

If you are confident that there's nothing on that browser you'll miss, you could try a one-time pull sync (possibly with starting from scratch / resetting cache beforehand).

I've tried that but the button "Trigger Sync from Scratch" was not doing anything noticeable. Alas. I could try disabling all other extensions on that particular Chrome browser and leaving just floccus enabled as sometimes, extensions like Blokada or Privacy Badger or ... or .... or .... that sniff Javascript can have bugs themselves and interfere with other extensions.

I am confident there's nothing on that browser I'll miss yes, a complete pull is a perfectly fine option if I can make it happen ;-).
