Server Side Cash Sales - Unexpected Error

I'm using the script below to create a cash sale when a customer is created in the system. On the last line (var id = nlapiSubmitRecord(cashsale, true);) I get the error; 'An unexpected SuiteScript error has occurred.'

Unfortunately, this does not give me much to go on. My first thought is that maybe I'm missing a required field but that is only a guess. Locations is turned off so it would not be that.

If anyone has any ideas, I'm open.:)



function afterSubmit(type)
{
var newId = nlapiGetRecordId();
var newCustomer = nlapiGetNewRecord();
var custentity = newCustomer.getFieldValue("entityid");
var newType = nlapiGetRecordType();

var cashsale = nlapiCreateRecord('cashsale');
