You actually don't need to re throw it, just leave the Promise.catch empty otherwise it will consider as un handle the reject and then wrap the code in a try catch and it will catch the error automatically which is passing down.

try{
  promise.then(function(result){
    //some code
  }).catch(function(error) {
    //no need for re throwing or any coding. but leave this as this otherwise it will consider as un handled
  });
}catch(e){
  console.log(e);
  //error can handle in here
}
