Record.getSublist() for custom sublist

Hello,

I am trying to perform an update using the "Script Debugger" and SS 2.0.

I have a record that is a custom record type, and I am trying to get values from a sublist of that record.

I have the following code:

 require(['N/search', 'N/record', 'N/log'], function(search, record, log){      var assetRecord = record.load({      type : 'customrecord_ncfar_asset',      id : '132'    });    //This assetLists array gives me a sublist with the name 'systemnotes'    var assetLists = assetRecord.getSublists();    for (i=0;i<assetLists.length;i++){      log.debug(assetRecord.getSublists()[i]);    }    //So I try to load that 'systemnotes' sublist    var objSublist = assetRecord.getSublist({      sublistId: 'systemnotes'    });    //This debug gives an error  log.debug(objSublist.id);    });
