ID: 15379 Title: aux_tags: aux_tag_id must exist in order to update Component: REST API Level: 1 Class: Bug fix Version: 2.3.0b1 This werk fixes a bug in the aux_tag put endpoint. Previously when sending a put request with a non-existing aux_tag_id, it would result in a 500 internal server error. Now we conform to our other endpoints and return a 404 problem response.
