Not sure what I have done wrong, I am following the quick start guide for mailchimp developers. https://mailchimp.com/developer/marketing/guides/quick-start/. I feel like I am missing a crucial step. I installed webpack. I am not getting the ping "everything is chimpy" instead its just perm reloading and highlighting requires in the sources tap in chrome dev tools.

It's highlighted 'require'.

const mailchimp = require("@mailchimp/mailchimp_marketing");

mailchimp.setConfig({
  apiKey: "7effff5342f8e4669e427c885b0b0088-us5",
  server: "us5",
});

async function run() {
  const response = await mailchimp.ping.get();
  console.log(response);
}

run();

this is my package.json
