Having problems going live

I had a running sandbox environment and once I tried to go to production, even after changing everything correctly I was still getting some errors. It is a node.js express app. Can someone tell me how to fix these?
Thank you very much!

Looks like your application of the Web Payments SDK is a MIME which isn’t supported. How are you wanting to implement the Web Payments SDK. :slightly_smiling_face:

I am using ejs as my view engine. I created the file card.html and then i include it on the checkout page to show the card.

const appId = ""; const locationId = "L6WB1C6A64GWE";
const Data = async () => {
  const res = await axios.get("/checkoutdata");
  const data = res.data;
  return data;

async function initializeCard(payments) {
  const card = await payments.card();
  await card.attach("#card-container");
  return card;
async function initializeGiftCard(payments) {
  const giftCard = await payments.giftCard();
  await giftCard.attach("#gift-card-container");

  return giftCard;

It was working perfectly fine in when I was in sandbox env
