messaging driver failing for "trace show" with: PRECONDITION_FAILED - inequivalent arg 'durable' for exchange 'openstack' in vhost 'openstack': received 'false' but current is 'true'

[Thomas Bechtold]

With osprofiler 2.3.0 on SLES12SP4 (OpenStack Rocky packages) I tried to use the messaging:// driver and got the following response:

# osprofiler trace show --json --connection-string messaging:// --transport-url rabbit://openstack:AQDykDn3Ybug@192.168.216.81:5672/openstack 25c49c14-c84c-4704-b715-0b4269b71ea0
No handlers could be found for logger "oslo.messaging._drivers.impl_rabbit"
