Javascript tracker example - only shows PageView

Hi. I tried to read as much of the documentation as possible on the javascript tracker, took the example from here: and ran it on a local site.

Here is a video showing the requests via the console:

The URL for the video is:

I loaded the example page and then clicked each button. Every request shows the same request, there are no custom schema/contexts or any event data. I haven’t setup the server to receive them yet.

I’ve tried this with 2.6.1, 2.7.0 and 2.8.0. Is there an issue with the example or something that I’m missing? Thanks in advance.
