Get Error : Firestore: The caller does not have permission to execute the specified operation. But I have already signed in

Question

I have this problem and try to fix with all solutions I had found,but still not works. My rules in firebase cloud firestore is :

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

And I had already enable Sign-in Method Anonymously.

Android

android/build.gradle:

        classpath 'com.android.tools.build:gradle:3.1.3'
        classpath 'com.google.gms:google-services:4.0.1'

android/app/build.gradle:

    compile project(':react-native-firebase')
    compile project(':react-native-fbsdk')
    implementation project(':react-native-firebase')
    implementation fileTree(dir: "libs", include: ["*.jar"])
    implementation "com.android.support:appcompat-v7:${rootProject.ext.supportLibVersion}"
    implementation "com.facebook.react:react-native:+"  // From node_modules

    implementation 'com.google.firebase:firebase-core:16.0.4'
    implementation 'com.google.firebase:firebase-auth:16.0.4'
    implementation 'com.google.firebase:firebase-firestore:17.1.0'

Testing.js:

firebase.auth().signInAnonymously().then(()=>{
        firebase.app().firestore().collection('Hello').doc('hello').set({
          id:'fadsa'
        }).catch((err)=>{
          alert(err);
        })
      })

Answer 1

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

change to this

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

Answer 2

This is an issue because of the rules that your DB currently has. Please check both datebases, Realtime and Firestore.

As in general, having full security rules or any other rule that is not complitely understood by RD or CF logic will get you that error everytime.

>     ".read": false,
>     ".write": false   } }

in Firestore you can configurate that as the following:

> service cloud.firestore {   match /databases/{database}/documents {
>     match /{document=**} {
>       allow read: if auth != null;
>       allow write: if auth != null;
>     }   } }

Answer 3

If you don't use authentication inside your app and only used the Firebase Firestore. So you can change it simply like this.

Change This

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

Into This

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

And last don't forget to publish these changes in order to save it.

If you have specified through timeStamp

If you have specified your Firestore rules through timeStamp then simply increase the length of duration of time.

rules_version = '2';
service cloud.firestore {
 match /databases/{database}/documents {
 match /{document=**} {
  allow read, write: if
    request.time < timestamp.date(2023, 3, 14);;
   }
  }
 }

Note: It is just for practicing and playing with Firestore data. If you want to build a production-level app then be sure to securely define your Firestore rules.
