Uncaught TypeError: undefined is not a function

[jnestour]

Hello, I am desperately trying to make this JS work but I am not a developer (though learning to code).

Here is the error I get in the console when loading the JS script and a vimeo video in an iframe. As far as I can see, I did everything by the book otherwise:

Uncaught TypeError: undefined is not a function vimeo.ga.min.js:8
(anonymous function) vimeo.ga.min.js:8

Would you have any pointers as to what could be the root cause at play?

Many thanks!

A good thing to do when troubleshooting an error would be to use vimeo.ga.js (instead of vimeo.ga.min.js). This will make provide more clarity into what is causing the error.
A shot in the dark, ensure the src of your iframe, which is the url to the vimeo video, does also include the player_id parameter, referencing the id of the iframe in on your page. For example:
&player_id=vimeo-player-1
