Listing network services results in "Error: Unable to execute query."

When I try to list any network services I get the following error.

~# vcd vapp network services nat list numuhukumakiakiaialunamor vAppNet-single
Usage: vcd vapp network services nat list [OPTIONS] <vapp-name> <network-name>
Try 'vcd vapp network services nat list -h' for help.

Error: Unable to execute query.

The vcd.log reports the following warning.

20-12-03 17:20:01 | client:2010 - _find_query_uri | WARNING :: Unable to locate query href for 'adminVApp' typed query.

The vcd_cli_error.log has the following backtrace.

Trying to list the firewall rules results in what looks like the same error.

Listing vApps, VMs and other operations are working fine. I have tried this against two different vCloud Director deployments and found the same behavior. The issue seems limited to all commands that are in "vcd vapp network services *"
