I have an Azure Web App (WebAppLinux) running an Angular application. The deployment is based on the Azure WebApp@1 task in an Azure pipeline.
Everything was fine until today. Without anyone having done a deployment, the website only shows an index page with the files stored in the home directory.
A re-deployment through the CI/CD pipeline is still successful. However, the error remains.
Was there any change to the Azure App Service that made my application incompatible?
The answer of LuisDev99 in https://stackoverflow.com/a/61707805/3809334 has solved the problem.
We had to add
pm2 serve /home/site/wwwroot --no-daemon --spa
to the Startup Command under Configuration, select the tab -> General Settings
In the past we had a startup script that called npx serve -s within our Angular application.
It seems that this way did not work anymore over the weekend. Maybe because there was a configuration change in the WebApp by Microsoft
Not an answer, but if you file an issue in https://github.com/Azure-App-Service/Linux/issues, that will help proceed with the next steps for investigation.
