Network Watcher - Topology - error: __init__() takes 1 positional argument but 2 were given

Describe the bug

Reporting with permission from user

error: init() takes 1 positional argument but 2 were given

I tried it without the –subnet option and got the same error. As you can see, the portal renders the topology using the same resource group and VNet names. Tried it this morning ONLY using –resource-group, and it worked! It should work with the other options too though, or they should be removed. I put two VNets in the resource group and the command returned the topology for both (as expected), but if I wanted it for only one VNet, it would be nice to be able to specify.

To Reproduce
See above.

Expected behavior
If this is a client error, the client should report back to the user with proper guidance on why the request failed.

Environment summary
CloudShell - unknown version
