Verification of environment variables and Firebase initialization
Firebase requires proper environment variables to be configured in your .env.local

Test your ability to read and write to Firestore
Common solutions for Firebase connection issues
400 Bad Request errors are often caused by Firestore security rules. Check the Firebase console and ensure your rules allow read/write access for your test operations.
// Sample rules that allow read/write for authenticated users rules_version = '2'; service cloud.firestore { match /databases/{database}/documents { match /{document=**} { allow read, write: if request.auth != null; } } }
If using Firebase from a different domain than your Firebase project, you might need to configure CORS for your Firebase project.
Check for any network restrictions that might be blocking connections to Firebase.
