Before I submit a bug report to Microsoft, I just wanted to check here first to see if anyone has come across this problem before.
I have set up an App Service Connection using a Management group following two tutorials, one on here Stack Overflow, and another on a blog post. Links Here:
Azure DevOps Service Connections not showing when setting up a new release pipeline
https://4bes.nl/2019/07/11/step-by-step-manually-create-an-azure-devops-service-connection-to-azure/
According to the Microsoft Documentation when you change to a Management Group you just reference that Management group in your code under Azure Subscription in your App Deployment Task in YAML.
Ref here: https://learn.microsoft.com/en-us/azure/devops/pipelines/library/connect-to-azure?view=azure-devops It states: If you're using YAML, copy the connection name into your code as the azureSubscription value.
Yet when I do this in my YAML code I get: ##[error]Error: 'subscriptionId' cannot be null.
I have a CLI task in my YAML code and when I upgraded that to Version 2 and referenced the ScriptType of PSCORE it works and finds the APP Service connection. Yet when it gets down to line 119 or under the heading of the task: Azure Web App Deploy: $(webappname), It then fails and gives me the error quoted.
Please if anyone has come across this before or knows how to fix it, I'd love to hear from you. If not it's a bug request to Microsoft. Again....
