Changing the difination . Not the place where passing the parameters

 // definition: 
 Call<ContextDto> ContextCall = _contextService.getContext(MinesiteID, lastModified == null ? "" : lastModified, UUID);
 // if the optinal paramters needs to work out by empty string, we can do some wrapper on it.
 // we can pass the null. it should alwasys work out.
  ContextDto contextDto = contextApi.Get(_minesiteID, Null, _uuid)
