What happened?

When using the Deploy an Azure App Service task to deploy an App Service, if the deployment fails then the task still marks itself as successful and continues.

Reproduction

1. On the App Server set the environment variable WEBSITE_NODE_DEFAULT_VERSION to 6.9.1, you may need to enable App insights too. This is to cause an error on deployment.
2. Use the Deploy an Azure App Service task in Octopus to deploy to this App Service.
3. The task should report it has completed successfully.
4. Open Azure portal and navigate to the App Service.
5. Open the Deployment Center and open the Logs tab.
6. The deployment will show as Failed.
7. Opening the details of the failure will show:
   • Updating submodules.
   • Preparing deployment for commit id '9cd85a6d1f'.
   • ❌ Generating deployment script.
   • Deployment Failed.
