Unable to Open Document Inside Tagged Folder that has Restricted File Access

Nextcloud 19.0.1

Trying to access documents inside a folder with a Restricted Tag that Blocks File Access (using Flow) to certain users.

Accessed the folder as a privileged user and was unable to open the document.

Error message:

Nextcloud logs as Admin

Collabora works fine on other documents that do not have the file access restrictions.

Any solutions to this? How can I help fix this? Happy to post more logs

Reference: #202 - marked as stale and wontfix - However, this problem persists.

EDIT: draw.io, a NC extension that edits diagrams work fine in the same environment, so this must be an issue with Collabora.

I need to get this working ASAP in production - any temporary solutions that works while maintaining the folder access control rights?

Start by reproducing the failure with a document in a folder using a Restricted Tag and Flow file-access restriction. Compare the Collabora failure with the working draw.io case, then inspect the attached Nextcloud admin logs and error message. Done means restricted documents open for privileged users without removing folder access controls.
