Scenario

I’m attempting to deploy a sample .NET Hello World Webapp to Azure, referencing a forked GitHub repository. The deployment process indicates that it is referencing my forked repository, but the GitHub Actions workflow does not trigger, and the web app is not deployed from the forked repo. I’ve tinkered with various settings with the terraform config, to no avail.

Issue

Despite configuring the repository and providing the GitHub authentication token, the GitHub Actions workflow is not triggered, and the web app is not deployed from the forked repository. I’ve also tinkered with setting the manual_integration variable of the source control slot to no avail.

Question:

Is there an additional authentication step or configuration that I’m missing between GitHub and the Azure portal to ensure the deployment triggers and pulls the code from my forked repository?

I am being patient post-deployment and waiting 10 minutes for the site to show. And it does work when deployed manually in the Azure portal.

Any help would be greatly appreciated! Thank you!
