Issue Summary

Knowledge Base visibility settings fail with "Stale view permission" error when the linked Confluence space

Steps to Reproduce

1. Link a Confluence space to a Jira Service Management project.

1. Ensure the Confluence space is using the updated permissions interface (where permissions are managed via Space Settings > Space Access > Members).

1. Navigate to JSM Space Settings > Knowledge Base.

1. Attempt to change the "Who can view" visibility setting (for example, from "All logged-in users" to "Only Confluence users").

1. Click Save.

Expected Results

The permission change is automatically applied to the Confluence space.

Actual Results

• The JSM UI displays the error: "Couldn't apply changes. Retry."

• In the browser's Network tab, a 409 Conflict or 500 Internal Server Error is returned from the /rest/knowledge-base/1.0/permissions/ endpoint.

• The response body in the browser console may contain a reference to a "Stale view permission."

Workaround

The permission must be updated manually from the Confluence side where the new UI is active:

1. Navigate to the affected Confluence Space > Space Settings > Space Access > Members.

1. Look for the information banner or setting that says "Any active user can view this space" and click "Disable this permission."

1. Return to the JSM space settings > Channels & self service > Knowledge Base page; the updated state will now be reflected correctly.
