Created a new project in Visual Studio based on a template using Angular, where another SampleDataController is being created.
Without touching anything, I try to start it and catch such a list of errors:

Tell me what I missed? In theory, a template project should work out of the box.
If you need more information, I will provide it.
npm install it spits out to me:
