az account get-access-token fails in Azure Cloud Shell

Description

Outline the issue here: Install the newer version of the az CLI client in the Azure cloud shell (the usual curl | bash install) and put it in the path. Try running:

$ az account get-access-token.

This produces "isMRRT" error: 
uros@Azure:~$ az account get-access-token 
'isMRRT'

The get-access-token is not supported to be used in cloud-shell, but i will fix that still. EDIT The fix will be in adal-python though. The fix was made in CLI 1.0 integrated by cloud console

[thangduong]

And 7 months later, the problem still happens: thang@Azure:~$ az ml env show -g MLModelHosting-rd-rg -n deploy1 A Cloud Shell credential problem occurred. When you report the issue with the error below, please mention the hostname ‘cc-efbb97af-236349040-krskc’ { “Azure-cli-ml Version”: “0.1.0a27.post3”, “Error”: “Could not retrieve token from local cache.” }

Great work guys.
