The requested module '@azure/arm-authorization' is expected to be of type CommonJS

I am using Node 14.5.0 with a default Express.JS installation. I need to leverage the Azure SDK for Node using Imports and have changed the default express require from:

const express = require('express')

to:

import express from 'express';

Express is able to load, but when I add the example SDK for authorization (https://github.com/Azure/azure-sdk-for-js/tree/master/sdk/authorization/arm-authorization) it is throwing the following error:

import { AuthorizationManagementClient, AuthorizationManagementModels, AuthorizationManagementMappers } from "@azure/arm-authorization"; ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ SyntaxError: The requested module '@azure/arm-authorization' is expected to be of type CommonJS, which does not support named exports. CommonJS modules can be imported by importing the default export. For example: import pkg from '@azure/arm-authorization'; const { AuthorizationManagementClient, AuthorizationManagementModels, AuthorizationManagementMappers } = pkg; at ModuleJob._instantiate (internal/modules/esm/module_job.js:98:21) at async ModuleJob.run (internal/modules/esm/module_job.js:137:5) at async Loader.import (internal/modules/esm/loader.js:162:24)

I have already added "type": "module", to my package.json and installed the modules listed in the Azure SDK page.

My App.JS page is as follows:

import express from 'express';
import * as msRest from "@azure/ms-rest-js";
import * as msRestAzure from "@azure/ms-rest-azure-js";
import * as msRestNodeAuth from "@azure/ms-rest-nodeauth";
import { AuthorizationManagementClient, AuthorizationManagementModels, AuthorizationManagementMappers } from "@azure/arm-authorization";
const subscriptionId = process.env["myguideforsubhere"];
const app = express()
const port = 5000

app.get('/', (req, res) => res.send('Hello World!'))

app.listen(port, () => console.log(`Example app listening at http://localhost:${port}`))

msRestNodeAuth.interactiveLogin().then((creds) => {
    const client = new AuthorizationManagementClient(creds, subscriptionId);
    client.classicAdministrators.list().then((result) => {
      console.log("The result is:");
      console.log(result);
    });
  }).catch((err) => {
    console.error(err);
  });

My Package.json is as follows:

{
  "name": "myproject",
  "version": "1.0.0",
  "description": "myproject",
  "main": "app.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "Me",
  "license": "ISC",
  "dependencies": {
    "@azure/arm-authorization": "^8.3.2",
    "@azure/ms-rest-nodeauth": "^3.0.5",
    "express": "^4.17.1"
  },
  "type": "module"
}

Does this look like an error in the SDK documentation where it can't use the imports as exampled but needs to be changed to require, or more likely, what have I done wrong?

See How to include commonjs module in ES6 module node app?

import { method } from 'commonjs-package';  // Errors
import packageMain from 'commonjs-package'; // Works

In your case, the azure sdk isn't written with "type": "module" so node treats it as a commonjs module, not an es6 module. So, you'll have to import and destructure in two separate steps:

import armAuth from "@azure/arm-authorization";
let { AuthorizationManagementClient, AuthorizationManagementModels } = armAuth;
