I'm going through this tutorial (https://developers.suitecommerce.com/show-a-shopper-their-product-reviews-with-product-data#title3) so I can display customer reviews on my site, with the only difference being that I'm doing this in an extension. I'm running on version 2019.2 but whenever I make a request to

services/MyReviews.Service.ss

I get a 404 error. I made sure to update my manifest JSON file. My

ssp-libraries

entry point is my ServiceController. Any thoughts on what could be going wrong?
