Without the paramater '--protected-settings' the command could not work

[tjxxxxx]

[Enter feedback here]
I do multiple test in my lab and I found, if I did not add this parameter '--protected-settings' the extension could not install successfully.

I must add this paramter even though with a empty value it could still work.
eg:
az vm extension set --name "VMAccessAgent" --publisher "Microsoft.Compute" --vm-name 2022windows -g 2022 --protected-settings "{}"

Could you please help to check if there are some issues with this command? As in the Powershell environment we do not need to add this paramter.

@zhoxing-ms for awareness

Further more, add the error message if we do not add this parameter.

I also check the extension log and agent log. The extension installed successfully but it could not enable successfully and directly return the error code. Please help to advice if we install vmaccess agent we must add the parameter or not. If yes, please help to update the document. If not please advice why this issue happen.

Thanks.

Since this error message is returned from REST service virtual-machine-scale-set-vm-extensions/create-or-update, so we need the service team to help investigate the root cause of this error message.

@nkuchta Could you please help take a look at this issue? Or could you route this issue to the right person?
