@firebase/database: FIREBASE WARNING: set at /messages/-L9JM5KcgMElxOVYNvyx failed: permission_denied

[Rajib Maitra]

Hi,

I just started to learn firebase recently and following a simple instruction to learn. I am not able to push data from a javascipt. I am using chrome browser. Will you please help?

Here are my codes:

index.html

    </div>

    <script src="https://www.gstatic.com/firebasejs/4.12.1/firebase.js"></script>

    <script src="main.js"></script>

 

</body>

</html>

And in main.js

/ Firebase

// Initialize Firebase

 

 var config = {

 apiKey: "AIzaSyBEJRD-gkjnvkJHwDZB9E8O_kIufQywi7c",

 authDomain: "contactform-8b572.firebaseapp.com",

 databaseURL: "https://contactform-8b572.firebaseio.com",

 projectId: "contactform-8b572",

 storageBucket: "contactform-8b572.appspot.com",

 messagingSenderId: "1006808566137"

};

firebase.initializeApp(config);

console.log(firebase);   >> This is fine...

 

//reference messages collection 

var messagesRef = firebase.database().ref('messages');

var data = {

    name: "rajib",

    phone: "2222222222"

}

messagesRef.push(data);

The firebase rule is:

service cloud.firestore {

  match /databases/{database}/documents {

    match /{document=**} {

      allow read, write;

    }

  }

} 

I am getting this error:

Hi Rajib,

it looks like you are mixing up firebase realtime database and firebase firestore. your rules are for firestore but your JS set up is for firebase. try to just use firebase first and set your rules accordingly, then move to firestore if you need to.

Worked for me, thanks. I was following codelabs.developers.google.com/codelabs/polymer-firebase-pwa and on firebase init had chosen both. Redid it and changed database on firebase console.
