Client doesn't have permission to access the desired data in Firebase

Question

I have a page that is calling addCheckin() method which is inside a controller. In the controller, I am trying to create a reference as follows:

var ref = firebase.database().ref("users/" + $scope.whichuser + "/meetings/" +$scope.whichmeeting + "/checkins"); 

$scope.whichuser and $scope.whichmeeting are the $routeParams that I am passing from another route. Here's my checkin controller-

myApp.controller("CheckinsController",     ['$scope','$rootScope','$firebaseArray','$routeParams','$firebaseObject',     function($scope,$rootScope,$firebaseArray,$routeParams,$firebaseObject){          $scope.whichuser = $routeParams.uid;         $scope.whichmeeting = $routeParams.mid;          var ref = firebase.database().ref("users/" + $scope.whichuser + "/meetings/" +$scope.whichmeeting + "/checkins");          $scope.addCheckin = function(){             var checkinInfo = $firebaseArray(ref);             var data={                 firstname:$scope.firstname,                 lastname:$scope.lastname,                 email:$scope.email,                 date:firebase.database.ServerValue.TIMESTAMP             }              checkinInfo.$add(data);         }  }]);/*controller*/ 

There are two errors that I am getting here-

Error 1:

Error: permission_denied at /users/Vp2P1MqKm7ckXqV2Uy3OzTnn6bB3/meetings: Client doesn't have permission to access the desired data.

Error 2:

Error: permission_denied at /users/Vp2P1MqKm7ckXqV2Uy3OzTnn6bB3/meetings/-KT5tqMYKXsFssmcRLm6/checkins: Client doesn't have permission to access the desired data.

And this is what I am tring to achieve-

Answer 1

Go to Firebase console of your app

Select Database From Side Menu --> Select Rule From tabs above --> Update your rule like this

{     "rules": {             ".read": true,         ".write": true     } } 

hope it solve your problem . thanks :)

Answer 2

Firebase project by default starts with Firestore as database.

This issue can happen if the application uses "Firebase Realtime Database" and permission for it are not configured. Read and write permission for Firebase Realtime Database should be explicitly granted.

To do so, in Firebase console, Database > Pick "Realtime Database" instead of "Firestore Beta" from the dropdown beside Database > Rules > Set

{ /* Visit https://firebase.google.com/docs/database/security to learn more about security rules. */ "rules": { ".read": true, ".write": true } } 

Hope that help!
