BMC Remedy AR system api

I am trying to extract details from incident，I set

entryListFields = [1000000161, 1000000217, 1000005781];entry_result = arserver_user.getEntry (form，entry_info_list[0].getEntryID(entryListFields);

however，this entry_result returns not only the 3 data fields requested, but also with these fields: 1, 30376000, 303524200, 303524300.

and when I use value = entry_result.get (1000000161);

It returns “None”
