Hi @abhilash-gsynergy,

2.82.0 is not the latest Azure CLI(2.83.0).

If you haven't already attempted to do so, please upgrade to the latest Azure CLI version by following https://learn.microsoft.com/en-us/cli/azure/update-azure-cli.

[yonzhan]

Thank you for opening this issue, we will look into it.

Thanks for the feedback! We are routing this to the appropriate team for follow-up. cc @zhangyd2015, @Frey-Wang, @Jingshu923.
