I am attempting to iterate through the Line items on a new Bin Putaway Worksheet. For some reason, I cannot seem to get the Line item data (Like the Item ID, Quantity, etc.). The binCount variable returns 500 (for the number of line items), but I cannot seem to get ahold of the Line data. Can anyone help me with how to get the internalID and quantity of each line? Here is my sample code:

var binWorksheet = record.create({type: record.Type.BIN_WORKSHEET, isDynamic: true, defaultValues: true});
            binWorksheet.setValue({
                fieldId: 'subsidiary',
                value: '2'
            });
            binWorksheet.setValue({
                fieldId: 'location',
                value: '2'
            });
            var binCount = binWorksheet.getLineCount({sublistId: 'item'});
// binCOunt === 500 here.
            for (var i = 0; i < binCount; i++) {

                var item = binWorksheet.getSublistValue({
                    sublistId: 'item',
                    fieldId: 'item',
                    line: i
                });
// item === '' here.

                binWorksheet.selectLine({
                    sublistId: 'item',
                    line: i
                });
                var item = binWorksheet.getCurrentSublistValue({
                    sublistId: 'item',
                    fieldId: 'item'
                });
// item === '' here as well.
            }

Thank you for any advice!

tried it out myself with different location

Interesting. I just ran the whole loop, and found that the very last item in the list (index 499) returns the item, but all the rest are blank...

Oh. I might have directed you to the suitescript supported records page had i known
