Solutions

1. Have another owner or admin add you to the collection instead of adding yourself.
2. Assign the collection to a group you belong to and manage membership through the group.

When it happens

Trigger: Thrown when an organization user attempts to add themselves to a collection via the user-collection assignment endpoint, which is disallowed; another admin must perform the assignment.

Common situations: See trigger scenarios.
