How to fix storage/project-not-found: No project configured for Cloud Storage in Firebase

// Web SDK (modular v9+)
import { initializeApp } from "firebase/app";
import { getStorage } from "firebase/storage";

const firebaseConfig = {
  apiKey: "YOUR_API_KEY",
  authDomain: "your-project.firebaseapp.com",
  projectId: "your-project-id", // Must be present and correct
  storageBucket: "your-project.firebasestorage.app",
  messagingSenderId: "123456789",
  appId: "YOUR_APP_ID"
};

// Initialize Firebase first
const app = initializeApp(firebaseConfig);

// Then get Storage reference
const storage = getStorage(app);

// Admin SDK (Node.js)
import * as admin from 'firebase-admin';

// Initialize with explicit project ID
admin.initializeApp({
  credential: admin.credential.applicationDefault(),
  projectId: 'your-project-id', // Explicitly specify project
  storageBucket: 'your-project.firebasestorage.app'
});

// Before
const firebaseConfig = {
  projectId: "my-app", // ✗ Wrong
  // ...
};

// After
const firebaseConfig = {
  projectId: "my-app-prod-abc123", // ✓ Exact project ID
  // ...
};

# .env.local
NEXT_PUBLIC_FIREBASE_PROJECT_ID=my-app-prod-abc123

const firebaseConfig = {
  projectId: process.env.NEXT_PUBLIC_FIREBASE_PROJECT_ID,
  // ...
};

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

console.log('Service account project:', serviceAccount.project_id);

import * as admin from 'firebase-admin';
import * as serviceAccount from './path/to/new-serviceAccountKey.json';

admin.initializeApp({
  credential: admin.credential.cert(serviceAccount),
  storageBucket: 'your-project.firebasestorage.app'
});

# Set the environment variable to your service account key
export GOOGLE_APPLICATION_CREDENTIALS="/path/to/serviceAccountKey.json"

import * as admin from 'firebase-admin';

admin.initializeApp({
  credential: admin.credential.applicationDefault(),
  projectId: 'your-project-id', // Explicitly specify
  storageBucket: 'your-project.firebasestorage.app'
});
