Issue: Unable to view/edit collabora files in opencloud

Observation:
Errors observed after I upgrade from open cloud release candidate to stable 4.0.0 version. Earlier in release candidate, collabora files able to view/edit them in the open cloud window.

Please guide me to debug this issue. Thanks in advance.

Seems like the file is not found on the storage. What kind of setup are you using?

@micbar

I'm using the docker setup. I have replicated the opencloud-full docker setup without tika server (running opencloud, wopi server, collabora, radicale).

I could see the opencloud is creating the file.

example: When I'm creating a new OpenSpeadsheet in opencloud drop down menu, I was able to create and view the file.
web banner shows: »test.ods« was created successfully
On storage I could find the file: ./data/storage/users/users/918834a0-ca8a-4ca1-aaca-a3b3b676ec7a/test.ods
opencloud file browser window shows the file existence. I'm unable to view/edit them directly.

I guess below uid_number is opencloud specific, not translated to unix file system.

I'm able to relate issue somewhat with cs3org/reva#2976

Is this causing issue?

@social-sparrow The issue with your xattrs seems serious.

@aduffeck @butonic Any ideas how to debug this further?

Waiting for debug steps and resolve the issue. Hope I can recover my setup this weekend.
