Cryptic error messages in OL3 v3.14.0

Question

I am getting cryptic error messages in my console with OL3 v3.14.0. I just upgraded. Here is an example:

Uncaught TypeError: (0 , d.f) is not a function

I have javascript source maps enabled. Can someone let me know how I should have my environment configured so that I can see the actual error?

If you use ol-debug.js this will give you a more informative error, and allow you to step through the library using a browser's developer tools.

When bug fixing, or developing, I usually have a commented out bit of html to pull in an ol-debug.js cdn as needed, and switch with ol.js :
