AzUrlShortner Azure webapp deployment error

[gilfoyle5]

Hi all, I am trying to deploy this fork to a webapp in Azure. I followed the guide to deploy it, but am getting this error under "Actions" in Github.
"Failed to find a default file in the app artifacts folder (wwwroot). Valid default files: index.html,Index.html.
If your application contains purely static content, please verify that the variable 'app_location' in your workflow file points to the root of your application.
If your application requires build steps, please validate that a default file exists in the build output directory."

For the "App location", I am using - src/TinyBlazorAdmin
API location is left blank.
App artifact location is set to - wwwroot

I'm not sure what I am doing wrong. Can anyone point me in the write direction? If I need to clarify or add any additional info here to help figure out what is wrong with it, please feel free to let me know. Thanks in advance!
