During Khaleesi a bulk introspection is ran to pull the node information. However if a failure occurs the error code is always returned as 0. For better error reporting, if a introspection fails (timeout/etc) return a proper status code. Dmitry quickly pushed a patch for this: https://review.openstack.org/#/c/253476/
Sorry, I didn't realize the fix is already available
