Hi,
Here is some additional information pertaining to the failures I am seeing
when invoking the tap-service-list and tap-flow-list commands. This is on a
multi-node DevStack environment (1 controller node, I network node and 2
compute nodes).
1. The tap-service-list command returns a failure when there are no
tap-services.
2. The tap-flow-list command returns a failure when there are no
tap-flows.
3. Both commands work as expected when the respective objects are present.
See example output (for tap-services) below.

Here is the output of tap-service-list with the "-debug" flag. The error is
being reported by neutronclient.shell.

It appears that other list commands associated with the neutron client also
show the same type of failure when their lists are empty.
