aaz generated delete command returns TypeError: 'NoneType' object is not callable for async delete operation

[ddadaal]

Hello, I used aaz-dev-tools to generate commands for this swagger. It defines a resource called storageclass, and its deletion operation is a long running operation swagger.

But when using the delete command, it returns error. The resource is actually deleted despite the error.

It seems to happen when the LRO is completed.

az cli (2.57), all extensions and aaz-dev-tools (2.6) are updated to latest.

How can I resolve this issue? Thanks!
