Please help, getting "POST http://custom-plugin.test/wp-admin/admin-ajax.php 400 (Bad Request)", not working in 2018

Is anyone else having trouble with this is 2018?

I have replaced my own code with the code from the downloadable example files, and it still isn't working. I even replaced my entire plugin folder with the example plugin folder, with the same results.

In my Chrome dev tools console I get "POST http://custom-plugin.test/wp-admin/admin-ajax.php 400 (Bad Request)".

I am not seeing the console.log message when I refresh, and my 'last_updated' value isn't updating in the database. Not sure if this just isn't working anymore since this course is a few years old now. Everything else up till now I've been able to get to work. Has anyone else gotten this to work recently?

Any help would be much appreciated!
