    The 404 error is because the passed table name is incorrect. CorporationProduct is the dataset name, while in your case, the table name should be product. 

     

    addRowsToDataset(datasetId, "CorporationProduct");

     

    You should also use a foreach loop in the getDataSetID function, otherwise when there're already other datasets, you code would go to error as well.

                datasetId = getDatasetId();
