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

[AmitBaranes]

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:

Any update?

@AmitBaranes can you share the command you ran? I am unable to reproduce with the command provided in the error message.

➜  ~ az aks enable-addons --addons kube-dashboard -g myresourcegroup -n newazcluster

@alinareti I try with version 2.0.66, it works well, looks like it's a cli issue.

[AmitBaranes]

@AmitBaranes can you share the command you ran? I am unable to reproduce with the command provided in the error message.

➜  ~ az aks enable-addons --addons kube-dashboard -g myresourcegroup -n newazcluster

getting this exception :

[kikicarbonell]

I have a same exception after creation of new aks cluster

[DevOpsFu]

I get the exact same issue. However, downgrading to v2.0.66 did not help for me @andyzhangx

[amolsh]

i am also getting same issue

The command failed with an unexpected error. Here is the traceback:

[palma21]

What Andy mentioned is we can't repro that with either 2.0.66 or 2.0.77

I see some outputs calling out python 2.7 and CLI 2.0.77 should be using python3

Could you check you are all using the latest CLI and the right python version is being referenced ?

az --version should also tell you the python location for you to check.

additionally could you run with --debug?

[amolsh]

I uninstalled azure-cli which was pointing to python2.7 and re-installed it

It looks like addon.config didn't get initialized before it's referenced here. @ganga1980 have you seen this CLI bug?

This is being addressed in this PR: https://github.com/Azure/azure-cli/pull/12250 cc @junsun17
