How to use Asynchronous Module Definitions(AMD) in SS2.1?

Question

I'm trying to import SheetJS Library to SuiteScript and read "xlsx" file data. I follow the SheetJS tutorial step, like this:https://docs.sheetjs.com/docs/demos/cloud/netsuite/

After upload file to the SuiteScript Folder, run the Suitelet still show error: "TypeError: Cannot read property 'read' of undefined".

That error in SheetJS means "The root cause is an undefined XLSX variable. This usually means the library was not properly loaded." But I already imported the "xlsx.full.min.js" file into NetSuite SuiteScript folder. How can I resolve that problem?

Here is my Code: JsLibraryConfig.json

{
    "paths": {
        "xlsx": "/SuiteScripts/xlsx.full.min.js"
    }
}

Suitelet

/**
 * @NApiVersion 2.1
 * @NScriptType Suitelet
 * @NModuleScope Public
 * @NAmdConfig  /SuiteScripts/JsLibraryConfig.json
 * @module jszip
 * @module xlsx
 */


define(['N/ui/serverWidget', 'N/search', 'N/redirect', 'N/format', 'N/runtime', 'N/record', 'N/url', 'N/currentRecord',  'N/file', 'jszip','xlsx'],
    function (serverWidget, search, redirect, format, runtime, record, url, currentRecord, file, JSZIP, XLSX) {
function onRequest(context) {
...
 var fileObj = file.load({ id: fileId });
                    var b64 = fileObj.getContents();
                    log.debug('b64', b64)
                    var workbook = XLSX.read(b64, { type: "base64" });
}
...
return {
            onRequest: onRequest,
        };
  });
