When data is migrated from another software platform it is possible that topics migrated would be considered “invalid” if created on Discourse. Common causes of “invalid” topics are `min topic title length`, `max topic title length`, and `title max word length`. If a user attempts to edit these topics (including changing category) they receive a `422` error, instead of the standard `Title seems unclear, is it a complete sentence?`.

Further, it’d be great if we could share the specific cause of the error (word is too long, for example) instead of the vague “title seems unclear”.
