azure static web app not starting after successful build and deployment

Question

Although my action, azure-static-web-apps-agreeable-sky-odd2be310.yml, appears to build and deploy correctly (green check), my app does not load. If I open the Build and Deploy job, and look at the Build and Deploy section I see:

Try to validate location at: '/github/workspace/FoodTruckNotification/FoodTruckNotification.Wasm/bin/Release/net7.0/dist'.
App Directory Location: 'FoodTruckNotification/FoodTruckNotification.Wasm/bin/Release/net7.0/dist' was found.
Try to validate location at: '/github/workspace/swa-db-connections'.

I have looked at the online help and made adjustments to my action, including removing the api_location and adding the app_build_command to the build and deploy section.

Hi @Leonard Kong

In looking at your yaml, it almost seems like you're building a Blazor server app. If you created your project using Visual Studio, and selected the ASP.NET Server hosting, then this may be the issue.

If you are, then you need to set to the app_location to the folder of the client app; using the example above, it would be /BlazorApp1.Client. Your app should start up, but if you're leveraging elements from the shared project, you'll likely run into reference issues. If that's the case, then you'll need to deploy your project to an app service as the Static Web App is client-side hosting.

EDIT 13 Sept 2023: We determined that there was nothing wrong with your yaml configuration. Your Uno landing page was displaying but your app wasn't available. You changed your yaml to deploy -c Debug configuration your application ran as expected. Upon further investigation, you discovered that a shared folder was missing from your -c Release configuration.
