NoteID error when creating new custom screen record from Move Screen

Hey guys,

I am having an issue with a custom action I have written, I think, in accordance with the T190 training course.

Below is the error I get:

This is my code for the method & the action:

//method declaration
private static void createQCCheck(AMBatch batch)
{
    using (var ts = new PXTransactionScope())
    {
        var qCEntry = PXGraph.CreateInstance<GCQualityControlEntry>();

        QualityControl doc = new QualityControl() { };
       // AMMTran batch = new AMMTran();

        doc = qCEntry.QCCheck.Insert(doc);
        doc.BatchNbr = batch.BatNbr;
        doc.Date = batch.TranDate;
        qCEntry.QCCheck.Update(doc);


        var batchEntry = PXGraph.CreateInstance<MoveEntry>();
        batchEntry.batch.Current = batch;




        foreach (AMMTran line in batchEntry.transactions.Select())
        {

                var lines = qCEntry.Details.Insert();
                lines.AMProdOrdID = line.ProdOrdID;
                qCEntry.Details.Update(lines);
        }

        qCEntry.Actions.PressSave();

        ts.Complete();

    }
}
//Action declaration
        public PXAction<AMBatch> CreateQCCheck;
         PXButton(DisplayOnMainToolbar = true)]
         PXUIField(DisplayName = "Start QC Checks", MapEnableRights = PXCacheRights.Select, MapViewRights = PXCacheRights.Select)]
        protected virtual IEnumerable createQCCheck(PXAdapter adapter) 
        {
           List<AMBatch> list = new List<AMBatch>();
            foreach(AMBatch batch in  adapter.Get<AMBatch>())
            {
                list.Add(batch);
            }

            var batches = AMBatches.Current;
            PXLongOperation.StartOperation(this, delegate () { createQCCheck(batches); });

            return list;
        }
