Firestore rules are blocking writes
Your Firebase project still has the default deny-all rules.
You need to update them once — it takes 30 seconds.
1 · Open your Firestore Rules:
Open Firebase Console → Firestore Rules
2 · Replace ALL the rules with this, then click Publish:
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /schools/{schoolId}/{document=**} {
allow read, write: if request.auth != null
&& request.auth.uid == schoolId;
}
}
}
3 · Come back here and click Try Again
