Applying SuiteScript on a NetSuite page got error "MODULE_DOES_NOT_EXIST"

Question

After applying Suitescript I am trying to deploy my user event script on vendor form but I always got "MODULE_DOES_NOT_EXIST" error.

ERROR STATEMENT: {"type":"error.SuiteScriptModuleLoaderError","name":"MODULE_DOES_NOT_EXIST","message":"Module does not exist: /SuiteScripts/AddFilterButton.js","stack":[]}

Here is SuiteScript:

/**
@NApiVersion 2.0
@NScriptType UserEventScript
@NModuleScope SameAccount
*/
define(['N/ui/serverWidget','N/log'], function (serverWidget,log) {

    function beforeLoad(context) {
        try{
            if (context.type === context.UserEventType.VIEW) {
                var form = context.form;
                
                var customButton = form.addButton({
                  id: 'custpage_filter_button',
                  label: 'Filter Button',
                });
                
                customButton.isDisabled = false;
                
            }
        }catch(ex){
            log.error({
                title: "Error",
                details: ex.message
            })
        }
    }

    return {
        beforeLoad: beforeLoad
    };
});
