What Is the Firestore Permission Denied Error?

The Firestore permission denied error appears when a user tries to read or write data to Firestore but lacks proper access rules in the Firebase backend.

📸 Use Screenshot Here: FlutterFlow Console showing red error message:

PERMISSION_DENIED: Missing or insufficient permissions.

Common Causes of the Error

• 🔒 Firestore Security Rules are too restrictive
• 👤 User is not authenticated
• 🧑‍🚫 Trying to access unauthorized document paths
• 🔁 Using `queryCollection` or `getDocument` incorrectly without access rules

⚠️ Avoid using allow read, write: if true; in production — this gives full public access to your database.

How to Fix Firestore Permission Denied in FlutterFlow

Step 1: Confirm Firestore Integration

1. Go to Settings > Firebase in FlutterFlow
2. Make sure Firestore is connected and active (green checkmark)

Step 2: Check Firestore Rules in Firebase Console

Go to the Firebase Console and check your Firestore rules.

Use the Following Rules for Authenticated Users:

firestore.rules

rules_version = '2';
service cloud.firestore {
  match /databases/{database}/documents {
    match /{document=**} {
      allow read, write: if request.auth != null;
    }
  }
}

✅ Copied!

Make sure your rules match the structure of your documents and user authentication status.

Update Firestore Rules – Step-by-Step

1. Visit the Firestore Rules Console
2. Select your Firestore project
3. Replace default rules with your tailored access, for example:

firestore.rules

match /yourCollection/{docId} {
  allow read, write: if request.auth != null;
}

✅ Copied!

Then click Publish.

💡 Tip: You can restrict access to user-specific documents using rules like:
allow read: if request.auth.uid == resource.data.user_id;

Case Example: Fixing This in a Real FlutterFlow App

Scenario: A user built a job board app and got permission denied errors while querying jobs.

Problem: Firestore rules were set to deny all access:

allow read, write: if false;

Solution: Update rules to allow authenticated reads on the collection:

match /jobs/{jobId} {
  allow read: if request.auth != null;
}

In FlutterFlow, queryCollection('jobs') was used with a filter:
user_id == currentUser.uid

🚀 Pro Tip: During development, you may temporarily use:
allow read, write: if true;
but always remove it before publishing your app for security.

❓ FAQ – Firestore Permission Denied in FlutterFlow

Why am I getting "permission denied" even though I'm logged in?

Your Firestore rules may not allow access. Ensure request.auth.uid matches the document’s user ID or that your rules permit authenticated users to access the data.

How do I fix Firestore permissions in FlutterFlow?

Update your Firestore rules in Firebase Console to allow authenticated user access, and verify your FlutterFlow app uses correct queries and user IDs.

Can I allow all users to read data temporarily?

Yes, by using allow read, write: if true; but don’t use this permanently in production as it exposes your data publicly.

How do I test Firestore rules?

Use the Firebase Emulator Suite or the "Rules Playground" in Firebase Console to simulate authenticated and unauthenticated requests.

Final Thoughts

If you’re getting a “Firebase connection failed” or “permission denied” error in FlutterFlow, don’t worry — this is common and easily fixable. Follow the checklist above and ensure your Firestore rules match your app’s security needs.
