I got this error during an upgrade to 0.17.5 Executing batch '0.17.4'* The following queries failed:* ALTER TABLE Port ADD CONSTRAINT `Port-FK-object_id` FOREIGN KEY (object_id) REFERENCES RackObject (id) -- Cannot add or update a child row: a foreign key constraint fails (`racktables/#sql-a76_b850`, CONSTRAINT `Port-FK-object_id` FOREIGN KEY (`object_id`) REFERENCES `RackObject` (`id`)) Should I be worried? What do I need to do to correct it? Craig.
