pipelines variable-group Not working with AzureCLI@2 Task

Trying to have a MS hosted DevOps agent query a Team project to select predefined variable groups. This works locally however; when coupled with the [Azure CLI Task](https://docs.microsoft.com/en-us/azure/devops/pipelines/tasks/deploy/azure-cli?view=azure-devops) Get an error
````Before you can run Azure DevOps commands, you need to run the login command(az login if using AAD/MSA identity else az devops login if using PAT token) to setup credentials. Please see https://aka.ms/azure-devops-cli-auth for more information.````

Try logging in via a PAT and script before this step and still not able to successfully run the az pipelines command
