azure-cli: argument of type 'NoneType' is not iterable when running az aks enable-addons

Describe the bug

Getting this error when running az aks enable-addons after I followed the instructions from azure dashboard :

The previous command that failed for me was az aks browse --resource-group with the following error : The kube-dashboard addon was disabled for this managed cluster. To use "az aks browse" first enable the add-on by running "az aks enable-addons --addons kube-dashboard".

Command Name az aks enable-addons

Errors:
