I'm trying to set the values of some custom segments on a custom record that we've created. I am able to set the values using SuiteTalk without issue, however when trying to set the values using SuiteScript 2.0 I am unable to get them to save. Either the value is blank or I get an exception saying invalid value (which is a valid value for the field)

Here is my current code:

  var brand = returnAuthRec.getSublistValue({           sublistId: 'item',           fieldId: 'custcol_cseg_rr_brand',         line: i,  });      var returnReasonRecord = record.create({      type: 'customrecord_return_reason',      isDynamic: false,  });     returnReasonRecord.setValue({       fieldId: 'custrecord_1682_cseg_rr_brand',       value:returnAuthRec.getSublistValue({           sublistId: 'item',           fieldId: 'custcol_cseg_rr_brand',           line: i,         }),        ignoreFieldChange: true,  });     returnReasonRecord.save();
