I am creating an Azure Container Service, using this command:

az acs create --name acs-cluster --resource-group ACSResourceGroup --orchestrator-type kubernetes 

And I am encountering this error over and over again.

usage: az acs create [-h] [--output {json,tsv,table,jsonc}] [--verbose]
                     [--debug] [--query JMESPATH] --resource-group

az acs create: error: Incorrect padding

I can't find enough documentation, or blogs for this error. I have been following the documentations all through out setting this up, but error in doing the ACS.

Hoping to find some answers here.
