I am getting an above error, when my app and mongo are running after ng serve command.
I added providers in @Component of home-list.
Does the error mean that my api is wrong (I also added CORS code) or Angular is wrong?

I got it. Import HttpModule in app.modules.ts was missing although I have not noticed it in the book.
