Hi @yves-chan,

2.56.0 is not the latest Azure CLI(2.57.0).

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.

Thanks for finding this issue. We will fix it in the next release of azure-cli.
