I'm using PDFMakeWrapper Server/side and nodemailer but when I generate a PDF is ok the problem is with the second one, it's generated but have like a cache or a copy of the last one pdf created, and go and go till I reset the server

here my code:

const printer = new Pdfmake({
    Roboto: {
        normal: __dirname + '/fonts/Roboto/Roboto-Regular.ttf',
        bold: __dirname + '/fonts/Roboto/Roboto-Medium.ttf',
        italics: __dirname + '/fonts/Roboto/Roboto-Italic.ttf',
        bolditalics: __dirname + '/fonts/Roboto/Roboto-MediumItalic.ttf'
    }
});

const doc = new DocumentDefinition();

async function FAL005(orden, Lote, materiales, lotes, cantidades){

const hoy = moment().format('DD/MM/yyyy');


doc.pageOrientation('landscape');
vigente');


doc.add(
    new Txt('Si usted esta consultando una versión de este documento, Asegúrese que sea la vigente').alignment('right').fontSize(8).end
)




const pdf = printer.createPdfKitDocument(doc.getDefinition());
let buffers = [];
pdf.on('data', buffers.push.bind(buffers));
pdf.on('end', () => {
    let pdfData = Buffer.concat(buffers);

});

HERE NODEMAILER

pdf.end();
