2 years ago Figured it out:
The System.NullReferenceException: Object reference not set to an instance of an object. error is due to Set-AzStorageBlobContent prompting for confirmation to overwrite the index.html file on the console.
Adding -Force flag to both of the Set-AzStorageBlobContent calls in the script resolves the issue and allows for updates to occur.

Issue Details
First run of this template works successfully, subsequent runs fail making this template unusable in a continuous delivery pipeline.
After deploying this template first time, I'm able to see the "Welcome" text on the index page of the frontDoorEndpointHostName output. However, any subsequent runs of this main.bicep file fail if any changes have been made.
It is my understanding that Bicep/ARM templates are designed to be Desired State Configuration and expected to be used as such (run many times to apply updates). However, this template doesn't seem to work in this fashion. What am I missing?
