Which Umbraco version are you using?
17.0.0-beta
Bug summary
When a user belongs to a user group that only has "Access to all documents" enabled (without read permissions) and tries to navigate to a content node, the user should receive a notification or message on the content node, like "Not found" or "Not authorized".
However, in version 17, the user only gets a blank page and a console error: GET https://localhost:44339/umbraco/management/api/v1/document/26abb1b0-c748-4be2-8ad7-be106fdabdee 403 (Forbidden)
Specifics

Steps to reproduce
- Create a UserGroup with Access to all documents enabled
- Create TestUser with the UserGroup
- Create a content node.
- Log in to the TestUser
- Navigate to the created content node
- See a blank/empty content node
Expected result / actual result
Expected: Some text should be displayed indicating "Not found" or "Not authorized", as was the case in previous versions.
Actual: A blank/empty content pane is displayed.
