@vilit1 Apologies for the late reply. Thanks for reaching out to us and reporting this issue. We are looking into this issue and we will provide an update.

@vilit1 Could you please run the below command and test ?

az rest --url "https://management.azure.com/subscriptions/{subID}/resourceGroups/{RG}/providers/Microsoft.ServiceBus/namespaces/{SBNamespace}/disasterRecoveryConfigs?api-version=2022-01-01-preview"

PS: Update your Subscription ID, RG Name and SB namespace in the placeholder.

@vilit1 We had a discussion over teams internally. You have confirmed that the az rest and az resource show command does help. However, your ask is particularly regarding the az servicebus georecovery-alias list CLI command.

The failure is occurring in this function: https://github.com/Azure/azure-sdk-for-python/blob/main/sdk/servicebus/azure-mgmt-servicebus/azure/mgmt/servicebus/v2022_10_01_preview/operations/_disaster_recovery_configs_operations.py#L511

Since this is Code is generated by AutoRest Code Generator. I am adding the Service team to look into this further.

Thanks for the feedback! We are routing this to the appropriate team for follow-up. cc @Saglodha.
