SuiteScript 2.0 server side code is referencing the document object?

Trying to create a bank deposit in a Map / Reduce script and I am getting the error:

"document" is not defined. (NLRecordScripting.scriptInit$lib#582)"

This seems to be some internal NetSuite functionality trying to reference the DOM but its server side code? Line 142 below is where the script blows up.

136 var nextRecord = record.create({ type: 'deposit', isDynamic: true, defaultValues: { disablepaymentfilters: true } });
137 nextRecord.setValue({ fieldId: 'customform', value: 1 });
138 nextRecord.setValue({ fieldId: 'account', value: bankAccount });
139 nextRecord.setValue({ fieldId: 'trandate', value: this.tranDate });
140 nextRecord.selectLine({ sublistId: 'payment', line: 0 });
141 nextRecord.setCurrentSublistValue({ sublistId: 'payment', fieldId: 'id', value: paymentRec });
142 nextRecord.setCurrentSublistValue({ sublistId: 'payment', fieldId: 'deposit', value: true });
