Get Related CONTACTS Id of a list of Accounts

Hi There, I am trying to get just the id's of a related contacts from a list of accounts, I can get it to output the full Json info , but i need just the Id's.

I keep getting the following error:

Failed to execute function
  • Argument type mismatch - Found 'NUMBER' but Expected '[KEY-VALUE, LIST, COLLECTION]' for the function 'get' Line Number:50

The code I am using is below:

AccountsList = {4994407000000930940,4994407000000372612,4994407000000372611};
info AccountsList;
ContactList = List();
for each accountele in AccountsList
{

relcont = zoho.crm.getRelatedRecords("Contacts","Accounts",accountele);
info relcont ;
ContactList.add(accountele.get("id"));
}
