i want to add user details in firestore when new user signs up but i m getting this error in console about "Undefined object"

function:

  exports.storeUserData = functions.auth.user().onCreate(event =>{
    const user = event.data;
     var db_uid_user = db_firestore.collection('users').doc(user.uid).set({
        'name' : user.displayName,
        'email': user.email,
        'phoneNumber': user.phoneNumber,
        'photoUrl': user.photoURL

    });

     console.log('User Add (uid)',user.uid);

});

So, i forgot that details that user object contain is limited with what kind of Auth your using.

For example: if you are using Email and password , your user object will have only email,password,uid.

hence

     'name' : user.displayName,        //invalid undefined object 
    'email': user.email,               //valid
    'phoneNumber': user.phoneNumber,   //invalid
    'photoUrl': user.photoURL          //invalid
