Firebase console gives error "Unexpected .read"

Question

I am trying to write the rules from Firebase console. But getting errors. Here is my very basic structure. Please help me.

service cloud.firestore {
  match /databases/{database}/documents {
    match /{document=**} {
      ".read": "auth.uid== User1"
    }
 }
}

Error: Error saving rules - Line 4: Unexpected '".read"'.

Answer 1

You're mixing up Firebase Realtime Database rules with Firebase Cloud Firestore rules. If you're following examples for Firestore, don't use examples from Realtime Database. For example, there is no ".read" rule in Firestore. Please read the documentation to get acquainted with the rules.
