File browser windows empty for copy/move in file but not elsewhere

Hi,
I’m not sure It’s a bug, but.

I met a stange problem with my nextcloud.
I’m not sure this create the problem, but before,

  1. I setup group folder, and create group folders with the same name some sharing folder already have.
    So I was having a public folder and create a public group folder.
  2. After that, in file, group folder appear with their setting name and sharing folder appear ‘renamed’ public-2 by the system.

Somewhere after that, here is my filde browser window

But, as mentioned before, in other place (not in file app), here is my file browser window

The “Tree is ok” there

I try to delete all files and folder, use occ command maintenance, repair, file
I remove group sharing to
empty cache
try other browsers and other compuetrs
nothing change

The only think I see is the ajax spinner not appear for the browser window in file, and appear before dispalying folders/files in the view.
And got an error in console
Uncaught TypeError: Cannot read property ‘contentWindow’ of undefined
at listener.js?v=a3cbea2a-39:82

Nothing in nextcloud.log

Can you help me repair the file browser ?
I’m lose, not understand why same object not working on file app but in Deck or everywhere else.

Tanks,
LauCo

Browser / PC : I try other browsers and other compuetrs on PC and Mac
No webserver log, no nextcloud log and console error juste say
Uncaught TypeError: Cannot read property ‘contentWindow’ of undefined
at listener.js?v=a3cbea2a-39:82

The problem is solved by ?
I was having some deck cards still linked to files.
I remove all broken link but nothing change, still having the trouble.
Do not Touch for some hours
After, I was setting the application’s group authorizations in installed app
And @ a moment, I say in myself ‘go have look in files’
So I’ll going to check my browser window and, miracle, it’s ok now.

I have this trouble since last Thursday, and remove all files friday.
This monday, still have the trouble.
So I suppose removing broken link and wait for some cron job was the think that’s solve the trouble.
If not, it’s by setting groups authorization an application !

Finally, the console error still present, so it’s not linked to my trouble as I was supposed.
LogLevel of nextcloud is set to 2 and log nothing about the trouble.
Appache log nothing about the trouble, loglevel set to warn

I don’t empty my browser’s cache from the trouble to the ‘automated’ solved trouble.

Thanks,
LauCo

We have a similar issue in files. On one of our nextcloud instances the copy/move in files is empty, though its not empty in any other apps. It is also not empty on another similar nextcloud instance. Both instances have Apache2, PHP 7.4, Nextcloud 20.0.4. Anyone else experience this issue? We don’t use deck (haven’t installed it) on our servers so I don’t think that is the issue. Though we had it installed sometime in the past.
