How do I upload an image to firebase storage using firebase admin sdk?

Question

I'm using Next.js here. I need to upload an image to my firebase storage. But it gives me a massive amount of errors. Okay, it gives me 1 error.

Init firebase admin sdk

// firebase.js
import * as admin from "firebase-admin";
import serviceAccount from "./firebase.serviceAccount.json";

if (!admin.apps.length) {
    admin.initializeApp({
        credential: admin.credential.cert(serviceAccount),
        databaseURL: process.env.NEXT_PUBLIC_FIREBASE_DATABASE_URL
    });
}

const firestore = admin.firestore();
const storage = admin.storage();

c
export { firestore, storage };

Uploading image

// route.js
import {  storage } from "../../firebase";

const router = async (req, res) => {
    // ...
    // Getting file from api request and so on...
    // ...

    const file = <an instance of File object>;

    const currentTime = Date.now();
    const fileName = file.name;

    const fileTitle = `${currentTime}-${fileName}`;

    const metadata = {
         contentType: file.type
    };

    const task = storage.ref().child(fileTitle).put(file, metadata);


    task.then(snapshot => snapshot.ref.getDownloadURL())
        .then(console.log)
        .catch(console.error);

};

export default router;

error

Failed to import the Cloud Storage client library for Node.js. Make sure to install the "@google-cloud/storage" npm package. Original error: Error: EIO: i/o error, read

Although I've installed @google-cloud/storage in my package list

1. Add storageBucket into your admin.initializeApp({})

if (!admin.apps.length) {
  try {
    admin.initializeApp({
      credential: admin.credential.cert(serviceAccount),
      databaseURL: process.env.NEXT_PUBLIC_FIREBASE_DATABASE_URL,
      storageBucket: process.env.NEXT_PUBLIC_FIREBASE_STORAGE_BUCKET,
    });
  } catch (e) {
    console.log("Failed to initialize App: " + e);
  }
}

2. Use admin.storage().bucket() instead of admin.storage()

import * as admin from "firebase-admin";
import serviceAccount from "./firebase.serviceAccount.json";

if (!admin.apps.length) {
    admin.initializeApp({
        credential: admin.credential.cert(serviceAccount),
        databaseURL: process.env.NEXT_PUBLIC_FIREBASE_DATABASE_URL
    });
}

const firestore = admin.firestore();
const storage = admin.storage().bucket();

export { firestore, storage };
