Has been blocked by cors policy react fetch firebase realtime database

likely error that arise to  cors blocked when using firebase is
when you initiate a put or get request with an incomplete firebase url
e.g
// wrong form
 this.http.get('https://******.firebaseio.com/data')   //this will throw an exception

// correct form                                                    
  this.http.get('https://******.firebaseio.com/data.json')
