The ValidationFailure{EXISTING_ITEM, "Canonical item metadata already exists, cannot create another"}

states that you you cannot overwrite an existing attribute metadata.

This can either result from a model update with an old version in the DB.

Or when trying to explicitly overwrite an attribute without specifying the overwrite="true" flag.
