Debugging Azure App Service issues

Debugging Azure App Service issues

Conflict (CODE: 409)

When deploying an app to Azure App Service using GitHub Actions, it is possible to encounter the error message Deployment Failed, Error: Failed to deploy web package using OneDeploy to App Service. Conflict (CODE: 409) (followed by the error Failed to deploy web package to App Service.).

This can occur when the app is over the resource limits, which can be the case where a previous deployment has failed and left behind files.

To fix this:

1. Access the Kudu Debug Console at https://<your-app-name>.scm.azurewebsites.net/DebugConsole
2. Navigate to the wwwroot folder using cd /home/site/wwwroot
3. Delete all of the existing contents of wwwroot using rm -rf /home/site/wwwroot/*
4. Restart the app via the Azure portal and try redeploying.
