Additional Context

Hi @vishalv-rafay,

2.41.0 is not the latest Azure CLI(2.74.0).

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.

Possible solution (Extracted from existing issue, might be incorrect; please verify carefully)

Solution 1:

For those seeking immediate workaround, look at downgrading az aks-preview extension. I did not spend time tracing at which exact release it got broken, but I found it works at below version:

az extension remove --name aks-preview
az extension add --name aks-preview --version 0.5.94

and you don't have to downgrade azure-cli

Solution 2:

The fix has been merged as part of this PR - #24270 and should be part of the next release. In the meantime, the workaround would be to downgrade to 2.40.0.

Hi @vishalv-rafay, I see you're on Azure CLI 2.41. I believe this issue was fixed in #24270. Can you upgrade your cli to the latest version (2.74) and see if the issue persists?

[mbifeld]

Hi @vishalv-rafay, can you confirm if upgrading the cli version worked?
