I am trying to append data to an excel via streams using exceljs but I am getting an error.

Can you please suggest how to handle the appending of data.

code

const dbClass = require(".././utils/dbPromises");
let client = await dbClass.createConnection();
let db = new dbClass(client);
res.setHeader("Content-Type", "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet")
res.setHeader("Content-disposition", `attachment;filename=report.xlsx`)
        const options = {
            filename: 'report.xlsx',
            useStyles: true,
            useSharedStrings: true,
            stream: res
        };

        const workbook = new Excel.stream.xlsx.WorkbookWriter(options);
        const worksheet = workbook.addWorksheet('report');

        for (let i= 0; i< 5; i++) {

            const statement = await db.preparePromisified(
                `SELECT  * FROM FUNCTION(i)) `
            );
              rs = await db.statementExecPromisified(statement, []);
            
      
            let stream = Readable.from(rs);

            stream.on('readable', () => {
                let data;
                while (null !== (data = stream.read())) {
                    worksheet.addRow(data);
                }
            });
        
         
            stream.on('end', () => {
                workbook.commit();
            });
     
        }
