Problem

When an administrator attempts to assign a space to a guest user who already has a space assigned, they encounter an erroneous and unclear error message:

We ran into a problem saving the changes.

Previously, the error message was specific and clear, stating:

Failed to save permission for guest: guest already has access to another space.

Environment

Confluence Cloud

Documentation:

• What can guests see and do in Confluence?
• Assign space access to guests

Steps to Reproduce

1. Login to Confluence Cloud as an administrator.
2. Navigate to the space permissions menu.
3. Attempt to assign a space guest permissions to a guest user who already has another space assigned to them.

Expected Results

The expected result is that a clear and specific error message is displayed, informing the user that the assignment cannot be made because the guest user already has access to another space.

Actual Results

Instead of the expected result, a vague error message, "We ran into a problem saving the changes," is displayed.

Workaround

There is currently no workaround for this issue.

Notes

This issue appears to have occurred after recent updates were made to the space permissions screen (https://community.atlassian.com/t5/Confluence-Cloud-Admins-articles/New-Space-Permissions-Experience/ba-p/2580660). Although the correct error message is present in the request, the UI is not displaying it.

This issue is causing confusion for administrators when assigning space to guest users, as the error message doesn't clearly explain what the problem is. A fix for this issue will improve user experience and minimize confusion when assigning spaces.
