Publishing Firestore rules: An unknown error occurred

Question

On a newly created project, I cannot publish any changes to the Firebase rules. Even simple changes like adding a newline to the end of the file or adding a space.

I feel like this may be a bug in Firestore but thought I'd ask here first...

Error saving rules –An unknown error occurred

service cloud.firestore {
  match /databases/{database}/documents {
    match /{document=**} {
      allow read, write: if false; 
    }
  }
}

If something in the console is not working the way you expect, contact Firebase support directly. firebase.google.com/support/contact – Gregory

Did you manage to get this issue resolved? – Koval

I contacted Google support and we eventually got it working by updating the security rules using the Firebase CLI. – Jedthus

Answer 1

I found that the Allow CORS: Access-Control-Allow-origin Chrome extension was the cause of this error for me. Disabling the extension fixed the error.

Install Firebase CLI in your command prompt, login in the firebase CLI, then open the .rules file with your editor(vscode, atom) and replace it with :

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

then deploy to firebase with from your command prompt with this command

firebase deploy --only firestore:rules

Had the same issue all of a sudden, "an unknown error occurred" for the Firestore security rules. Fixed it by updating it through the Firebase CLI.

So, in the terminal do the following steps:

1. npm install -g firebase-tools
2. firebase login // finish the login procedure

// Set up Firestore in your project directory, creates a .rules file

3. firebase init firestore

//Update the firestore.rules file that you can find in the root of the directory.

// Save and deploy your .rules file

4. firebase deploy --only firestore:rules

Answer 4

The only way i got it to work is through CLI, Init it, chose the existring project you have and change the rules in the .rules file, then deploy them.

Answer 5

Simply opening Firebase storage console on incognito and changing rules then, helped for me.

If that doesn't work, try:

1. Turn off all extensions in your browser.
2. Save the rule
3. Turn on extensions again
