I created an app using dotnet new angular template.
Executed dotnet run and everything works.
I pushed the code to GitHub and set continuous deployment in Azure to build from that GitHub repository.
However the build fails, I turned on Development mode in Azure to see all the errors, and this is what I get, tons of text, but I cant figure out why build failed on Azure.
An unhandled exception occurred while processing the request.
