I tried to store data in firebase database but the following errors occurs:

Data Writing to firebase
FirebaseDatabase firebaseDatabase=FirebaseDatabase.getInstance();
DatabaseReference databaseReference=firebaseDatabase.getReferenceFromUrl(Constants.FIREBASE_ACTIVE_LIST_URL);
DatabaseReference ref=databaseReference.push();
HashMap<String,Object> timeStampCreated=new HashMap<>();
timeStampCreated.put(Constants.FIREBASE_PROPERTY_TIMESTAMP, ServerValue.TIMESTAMP);
ShoppingList newShoppingList = new ShoppingList(userEnteredName, owner,timeStampCreated);
ref.setValue(newShoppingList);
AddListsFragment.this.getDialog().cancel();
