Az cli error when trying to create an AKS cluster

This is autogenerated. Please review and update as needed.

Describe the bug

The error is given by az cli task on Github Actions and I have reproduced it manually by passing "y | " to az aks command to avoid confirmation for: "It is highly recommended to use USER assigned identity (option --assign-identity) when you want to bring your ownsubnet, which will have no latency for the role assignment to take effect. When using SYSTEM assigned identity, azure-cli will grant Network Contributor role to the system assigned identity after the cluster is created, and the role assignment will take some time to take effect, see https://docs.microsoft.com/azure/aks/use-managed-identity, proceed to create cluster with system assigned identity? (y/N): "

Command Name az aks create

The command failed with an unexpected error. Here is the traceback:

No worries @yonzhan @RakeshMohanMSFT, I’ve just realized that it’s my fault. I had a commented line between parameters so the command wasn’t launched correctly. Once fixed it works correctly.

Sorry for the inconvenience.
