How to create a customer with multiple subsidiaries using suitescript

Hi,

I’m trying to create a customer record  with multiple subsidiaries using a Restlet service. I’m able to run the code below on the debugger tool without any errors, but when I try to use the same code on a suitescript it returns the following error: You entered an invalid field value 3 to the following field: subsidiary”

const customerRecord = record.create({type: record.Type.CUSTOMER, isDynamic: true});
customerRecord.setValue({ fieldId: "isperson", value: "T" });

customerRecord.setValue({ fieldId: "firstname", value: "FirstName" });

customerRecord.setValue({ fieldId: "middlename", value: "null" });

customerRecord.setValue({ fieldId: "lastname", value: "LastName" });

customerRecord.setValue({ fieldId: "companyname", value: "" });

customerRecord.setValue({ fieldId: "entitystatus", value: "13" });

customerRecord.setValue({ fieldId: "subsidiary", value: "1" });

customerRecord.setValue({ fieldId: "email", value: "teste@teste.com" });
customerRecord.selectNewLine('submachine');

customerRecord.setCurrentSublistValue({ sublistId: 'submachine', fieldId: 'subsidiary', value: 3 });

customerRecord.commitLine({ sublistId: 'submachine' });
customerRecord.save();
