When deploying an Azure Event Grid subscription, we started receiving a "Resource cannot be updated during provisioning" error starting end of last week, out of nowhere, with no change to the ARM template which had been working for several weeks.
The Continuous Deployment ARM Template is basically deploying the latest AppSettings of an Azure Functions App along with an Event Grid Topic Subscription. Here are the important steps from the CD, it fails at the first step, which executes the ARM template:
Error Message from the Continuous Deployment in VSTS:

When looking at the Event Grid Activity Log in the Azure Portal, I found the following information, confirming that the subscription is failing:
