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

from that:

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;
    }
  }
}
