Users with whom I have shared a sub-folder cannot upload to it

[PocketFR]

Hello,

I have created a group folder in which I share a subfolder with another user of my nextcloud instance (outside the group)

This user can't upload documents in this folder even though the share allows him to.

See the log below:

He can however create text documents and folders in this folder.

The problem does not occur with link sharing.

I tried the same folder scheme without using group folders and it works.

Configuration : new installation of nextcloud 21.0.0 updated to 21.0.1 then installation of groupfolder 9.0.0.
No other application than the preinstalled ones has been added.

I was just about to create an issue for this, too. I can confirm the behaviour.
I upgraded from 20.0.8 to 21.0.1 and experienced this issue. PHP version 7.4

[saschier]

I have the same problem with nextcloud 20.0.9 and groupfolder 8.2.0.

[RP-666]

Same here. Nextcloud 21.0.1 - PHP 7.4 - Group folders 9.0.0

[BadBone2k]

Same error here, Nextcloud 21.0.1 and groupfolders 9.0.0.

Same behaviour here, but with different Sabre error:

I have the same error an accidently opened another issue just 5 minuntes ago. We get "Could not rename part file to final file"-Errors when trying to write files in shared folders which sit in a group folder (group folder/shared folder/...) on two different servers which were updated to version 21.0.1.1. The two backup servers with version 20.0.9 run fine. Any ideas?
