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”.
