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 :

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

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.

> // Full security
> 
> {   "rules": {
>     ".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.

Answer 4

Just to point out, this can also happen if you have a function that runs (can be periodic) it ran after you are signed out.

Answer 5

I had the same error with my flutter application on Android Stuido and when I check the rules I saw there was a time limitation for allowing read and write operations. So I just extended the time period as below:

rules_version = '2';

service cloud.firestore {

match /databases/{database}/documents {

match /{document=**} {

  allow read, write: if

      request.time < timestamp.date(2022, 9, 29);

}

}

}

Answer 6

Just want to add that this error can also happen if you enabled "App check" in Firebase and enforced the checking of the App check token but the token is missing in the requests.

In that case, you need to add the plugin firebase_app_check .

Answer 7

I had the same error, I struggled a lot because I missed "No App Check token for request." warning.

If you enforced Cloud Firestore on app check, must configure, unenforce or add token. [firebase appcheck]

Answer 8

Update your rules file on Firestore console. Set permission to read and write to true.
