I am getting error on this code/setup, am I missing something?

I have the same issue. For my part I put the scripts in the head section. I am running it in Firefox 54.0.1 (32-bit). I get the same error in Chrome 59.0.3071.115 64 bit. Do you need other details about the environment?

I think this error was introduced at Leaflet 1.1.0. I noticed it on an app I recently upgraded, but don't notice it when using 1.0.3.

I have downgraded my Leaflet to 1.0.3 for now to make it work. Thanks @calvinmetcalf for a quick response.
