@qwordy Please take a look

[qwordy]

Could you share the complete commands? What extension are you using? How do you create the vmss and set the extension? Thanks.

HI @kotharij could you pls share more context on your vmss extensions setup? we did a fix to avoid NoneType exception but show empty to indicate no extension. Need your input on the specific case to figure out why no extension found. thanks.

[qwordy]

Close the issue for now. The fix will be available in the next version of Azure CLI. It will be released on 03/10/2020.

@kotharij feel free to open a new issue when you see extension listed is not matching expectation with reproduce steps, especially extension setup detail. thanks.
