Answer 1

I encountered the same issue if I use popper.js from CDN network like cdnjs.

If you observe the source code of Bootstrap 4 examples like for example Navbar you can see that popper.min.js is loaded from:

I included that in my project and the error is gone. You can download the source code from

https://getbootstrap.com/docs/4.1/assets/js/vendor/popper.min.js

and include in your project as a local file and it should work.
