next-transpile-modules: TypeError: Cannot set property 'styles' of undefined

• I HAVE READ THE FAQ AND MY PROBLEM WAS NOT DESCRIBED THERE
• I WILL GIVE 10$ TO CHARITY IF MY SOLUTION WAS ACTUALLY IN THE README/FAQ

Are you trying to transpile a local package or an npm package? https://www.npmjs.com/package/@adobe/react-spectrum

Describe the bug Not sure what styles are undefined. I actually updated my single page to say import mystyles but I am still getting a message that TypeError: Cannot set property 'styles' of undefined.

To Reproduce I have config like this:

const withPlugins = require("next-compose-plugins");
const withCSS = require("@zeit/next-css");
const withTM = require("next-transpile-modules")(["@adobe/react-spectrum"]);

module.exports = withPlugins([withCSS, withTM], {
  reactStrictMode: true,
});

I run npm run dev and the ONLY page I have is this:

import mystyles from "../../styles/index.module.scss";
export default function Index() {

My _app.js has these imports:

import { SSRProvider, Provider, defaultTheme } from "@adobe/react-spectrum";
import "../../styles/globals.scss";
import type { AppProps } from "next/app";

Expected behavior For things to compile
