UNEXPECTED_ERROR on journalentry nlapiSubmitRecord()

I am trying to create a Custom Transaction Type record. So far I've worked past a whole boatload of errors and now I'm ready to submit the new customtransaction_commission_accrualrecord. When the data is submitted to NetSuite using the nlapiSubmitRecord() function an error of UNEXPECTED_ERROR is thrown and no details are given. Any ideas of how to proced when this error is the result.

Here is the offending code:

 function setPeriodCommissions(postedData) {      try {          var je = nlapiCreateRecord("customtransaction_commission_accrual");          je.setFieldValue("trandate", nlapiDateToString(new Date()));          je.setFieldValue("currency", nlapiFormatCurrency("USA"));          je.setFieldValue("exchangerate", 1.00);            // create the line items; first work control account          je.selectNewLineItem('line');          var accountId = ifxFindRecord.returnRecordId("account", "number", postedData.GLAccount);          je.setCurrentLineItemValue('line', 'account', accountId);          je.setCurrentLineItemValue('line', 'amount', postedData.CommissionAccrual);          je.setCurrentLineItemValue('line', 'memo', postedData.CommissionType);          je.commitLineItem('line');            var transNum = nlapiSubmitRecord(je, true, false); //return JE transaction number      }      catch(e) {      }  }    var data = {      "GLAccount": "2155",      "CommissionType": "Primary Bonus",      "CommissionAccrual": 100,      "CommissionPayout": 100  };    setPeriodCommissions(data);
