Cannot read property 'filter' of undefined

[joshcsullivan]

Describe the bug
I stupidly updated NC Bookmarks to 3.1.0 without checking how long it's been out (~2 hours), and floccus immediately came up with this error in Brave (Chromium): Cannot read property 'filter' of undefined. Firefox (which uses another server folder) comes back with: this.children is undefined. I've tried removing the account, removing the local bookmarks and setting sync up again, but still having the same issue.

To Reproduce
Steps to reproduce the behavior:

1. Upgrade to NC Bookmarks 3.1.0
2. Either force sync or wait for floccus to sync, and it will come back with an error.

Expected behavior
floccus syncs local changes to NC Bookmarks.

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

Desktop (please complete the following information):

• OS: Windows Enterprise 1909
• Browser: Brave (Chromium)
• Browser Version:Version 1.9.76 Chromium: 81.0.4044.138 (Official Build) (64-bit)
• Floccus version: 4.1.0
• Floccus sync method: NextCloud Folders

Server (please complete the following information):

• OS: Ubuntu 18.04.4 LTS
• Nextcloud version: 18.0.4
• Bookmarks app version: 3.1.0

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://klehranlage.net/index.php/s/7nn82NSBsfQKdsJ

Additional context
I also use nextBookmark on iOS, and it is syncing correctly, just as a point of reference that NextCloud sync is still working.

Cheers,

Same. Nothing new to contribute except that it's affecting me the exact same way. It appears the update to Nextcloud Bookmarks 3.1.0 is the casue.

[marcelklehr]

Yep. v3.1.1 is out already. Update the bookmarks app to get the fix :)

[marcelklehr]

It's a double bug. A bug in nextcloud bookmarks caused a bug in floccus 🙀

Same here

Maybe I'm doing this wrong, but since I haven't receive the notification to install the Nextcloud Bookmarks update I looked to see if I could manually install the fix. The diff between 3.1.0 and 3.1.1 (other than version numbers) is one character on one line.

See nextcloud/bookmarks@v3.1.0...v3.1.1

I made the change on line 665 (per the diff file) and restarted apache, but floccus still isn't working.

Again, maybe I did the patch wrong (I only changed line 665).

Anyone know how to force Nextcloud to look for app updates?

[marcelklehr]

The floccus update of today definitely fixes the client-side bug, so until the bookmarks update reaches you, an update of floccus should take care of things.

The new Firefox extension update 4.2.0, it started working immediately, without the 3.1.1 NC Bookmarks update yet.

No new Chrome Extension of yet, so waiting patiently.

Thanks for the quick turn around!
