Use ConnectedServiceNameARM instead of azureSubscription in AzurePowerShell tasks in Azure DevOps YAML pipelines

tl;dr

Don't get fooled into providing an Azure Subscription name to a AzurePowerShell task in an Azure DevOps YAML pipeline, just because the input argument is named azureSubscription. It really needs the name of an Azure DevOps Service Connection!

For AzurePowerShell tasks use the ConnectedServiceNameARM input name instead of the misleading azureSubscription alias.

The Context of the Error

I made a copy of an Azure YAML pipeline I found on the internet as a baseline for what I needed.

Pass variables between job steps in Azure DevOps YAML Pipelines

Example YAML pipeline

The example (see sample-azure-pipeline.yml) uses the pwsh shortcut for the PowerShell task so it works across platforms.

In Step 1 the inline PowerShell script logic determines and sets the value of the IsFooBar variable. It uses "logging commands" to set the variable.

Write-Host "##vso[task.setvariable variable=IsFooBar]$IsFooEqualToBar"

Disable Azure Function if Exists using YAML Pipeline

The disable-function-if-exists.template.yml below is a sample Azure DevOps YAML pipeline template that can be used to disable an Azure Function if it exists.

In some deployment scenarios you may need to disable an Azure Function, such as a queue triggered function, before deploying down stream resources. The function to be disabled may not exist the first time the deployment pipeline is run in a particular environment, so the template checks for its existance before attempting to disalbe it.
