Try to use require(“module”) or if that's the way you doing it, you sould try import("module"). Maybe this will help.

I had this same issue yesterday and followed this answer from github and I add '.mjs' to my configureWebpack extensions. and to the rules. Just make sure to appear before .js'. So basically you will have as follow :

const config = {
 configureWebpack: {
   resolve: { // .mjs comes before .js 
     extensions: ['*', '.mjs', '.js', '.json', '.gql', '.graphql']
   },
   module: {
     rules: [ 
       {
         test: /\.mjs$/,
         include: /node_modules/,
         type: 'javascript/auto'
       },
       // all the other rules
     ]
   }
 }
}

module.exports = config
