az aks check-network command cannot locate resource group.

[HeyNaNd0]

Describe the bug

When executing the command az aks check-network outbound, it accepts the resource group as an input but subsequently reports that it cannot locate it. Interestingly, when the debug flag is utilized, the very same resource group that the error message claims cannot be found is present in the debug output.

example:

az aks check-network outbound --name --resource-group [--custom-endpoints ] [--node-name ]

@yonzhan any update about this issue?
This error is reproducible when creating AKS clusters with custom node resource group name.

The "az aks check-network outbound" command seems to work only in clusters with the default "MC_*" node resource group name.

Example:

$ az aks create -n akstest -g akstestrg --node-resource-group aksnoderg

$ az aks show -n akstest -g akstestrg --query nodeResourceGroup -o tsv
The behavior of this command has been altered by the following extension: aks-preview
aksnoderg

$ az aks check-network outbound -n akstest -g akstestrg
Get node pool VM set type: VirtualMachineScaleSets
(ResourceGroupNotFound) Resource group 'MC_akstestrg_akstest_uksouth' could not be found.
Code: ResourceGroupNotFound
Message: Resource group 'MC_akstestrg_akstest_uksouth' could not be found.
