Public bug reported:
A TypeError was thrown during a synchronization
command(eutron-ovn-db-sync-util) execution. By checking the error call stack,
it was found that it was an error during the creation of QoS. After analysis,
there should be a port in the Neutron database, but not in the ovn-nb database.
At this time, when executing the UpdateLSwitchQosOptionsCommand to create a
logical port and update the QoS, it was found that the port_id is None.
tracking variable port_id is obtained by executing AddLSwitchPortCommand. It
should be that this command did not set the port_id correctly caused. Analyzing
AddLSwitchPortCommand, it was found that if the port already exists, no result
was set.
This seems a bit contradictory. It was determined earlier that the port does
not exist, but later it does. I think this situation may occur when executing
synchronization commands and calling the API that creates the port. This
operation is not very reasonable.
But I think the AddLSwitchPortCommand command should return consistent
results. This issue should be fixed.
