Why firebase.initializeApp return a FirebaseError: "projectId" not provided" with import/export syntaxe?

I dowloaded a correction folder for ecomerce project.
This is the error in console after the ‘npm start’ command:
The problem can’t come from the firebase object congig because I checked many time, I create a new one that I tried in another project olready in line and it works well.
I tried everything. I looked for everywhere in internet. I didn’t find the solution who works for me.
I think the problem come from import/import syntaxe.
if anyone could try to make this project work and tell me what’s wrong that would be great:

here is a part of my server.js file:

import express from "express";
import bcrypt from "bcrypt";
import { initializeApp } from "firebase/app";
import { getFirestore, doc, collection, setDoc, getDoc, updateDoc, getDocs, query, where, deleteDoc, limit } from "firebase/firestore";
import stripe from "stripe";

// Your web app's Firebase configuration
const firebaseConfig = {
  type: "service_account",
  project_id: "ecom-website-ef3e5",

};
// Initialize Firebase
const firebaseApp = initializeApp(firebaseConfig);
const db = getFirestore(firebaseApp);

// init server
const app = express();

// middlewares

const secretAccessKey = process.env.AWS_SECRET_KEY;

aws.config.update({
  region,
  accessKeyId,
  secretAccessKey,
});

// init s3
const s3 = new aws.S3();

// generate image url
async function generateURL() {
  let date = new Date();

  const imageName = `${date.getTime()}.jpeg`;

  const params = {
    Bucket: bucketName,
    Key: imageName,
    Expires: 300, // 300 ms
    ContentType: "image/jpeg",
  };

  const uploadURL = await s3.getSignedUrlPromise("putObject", params);
  return uploadURL;
}

app.get("/s3url", (req, res) => {
  generateURL().then((url) => res.json(url));
});

// routes
// home route
app.get("/", (req, res) => {
  res.sendFile("index.html", { root: "public" });
});

// signup

});
