Error: 'set' object is not subscriptable

[SA0TAY]

Due to similar issues as in #511, I'm using vcd-cli==22.0.0 and pyvcloud==21.0.0, but I'm experiencing the same problem installing the latest from git with pip3 install git+git://github.com/vmware/vcd-cli.git.

Commands such as vcd cse template list work just fine. When I try to make a new cluster, however, this is what happens:

(cse) ubuntu@staging-vps:~$ vcd cse cluster create TEST
Usage: vcd cse cluster create [OPTIONS] NAME
Try 'vcd cse cluster create -h' for help.

Error: 'set' object is not subscriptable

I am on Python 3.7.5 in a virtualenv, and the installed packages are as follows:

This is what appears in the logs, minus identifying bits:

container_service_extension.exceptions.CseResponseError: 'set' object is not subscriptable

Searching the tracker from the container-service-extension repo gave me vmware/container-service-extension#544, but I'm not sure how it relates.

I think this error is a bug in CSE which we found after releasing 2.5.1. If you send wrong payload to CSE, the payload verifier tries to create a set of missing/invalid keys. The bug being we use [] operator on the set, which is not supported.

I am sure that this bug is related to malformed payload. Can you not send null in the payload. Just drop the key. num_workers can be set to 1.
