Running migrate-flat-routes using convention flat-folders ESM error

[jcjp]

Description:

Hi i'm trying to migrate my flat files convetion to a flat-folders using the migration tool but blocked due to the ESM error. I am also using Vite for bundling.

// remix.config.js
import { flatRoutes } from 'remix-flat-routes'

/**
 * @type {import("@remix-run/dev").AppConfig}
 */
export default {
  // ignore all files in routes folder to prevent
  // default remix convention from picking up routes
  ignoredRouteFiles: ['**/*'],
  routes: async defineRoutes => {
    return flatRoutes('routes', defineRoutes)
  },
}

Error:

npx migrate-flat-routes ./app/routes ./app/flat-folder-routes --convention=flat-folders

        const remixConfig = require(path.join(process.cwd(), 'remix.config.js'));
