Module Does Not Exist error when calling a Restlet

@NApiVersion

I created a Restlet. Very simple Hello World.js


/**
*@NApiVersion 2.x
*@NModuleScope Public
*@NScriptType Restlet
*/

define([],function() { // NetSuite's AMD pattern
    function onRequest_entry(context) { // Suitelet entry function receives a context obj
        context.response.write('Hello World'); // Write a response using the context obj
    }
    return {
        get: onRequest_entry // Function assigned to entry point
    };
});


I went into Customizations, uploaded the script (I saved it into the SuiteScripts Folder), and deployed it following the info in the help center.

I then called it from Postman using the URL indicated in the Deployment record, and I get the following Error returned:


Status 400 Bad Request
