Tag slug already defined
HTTP status 409 Conflict, code TAG_SLUG_TAKEN.
What it means#
A tag with that slug is already defined in the organisation. Slugs are unique per organisation, and an archived definition keeps its slug, because references store the slug.
What to do#
Use the existing definition (restore it with archived: false if it is archived), or choose another slug.
