Comment 11 for bug 1682423

When adding an instance by CLI, a 404 will be returned too.
But the error has no effect except the instance is added by dashboard.

To override the error i added a sleep at 2360 in file /usr/lib/python2.7/site-packages/nova/compute/api.py to delay the fetch request.

time.sleep(1.0)
try:
if uuidutils.is_uuid_like(instance_id):
    LOG.debug("Fetching instance by UUID",
    instance_uuid=instance_id)

I attached the debug output and the nova-api.log.
