Problem with MySQL connection PYTHON FLASK [closed]

Im trying to implement a pdf report downloader with fpdf

def download_report():

    try:
        conn= db.connection
        cursor = conn.cursor(pymysql.cursors.DictCursor)
        sql= "SELECT * FROM productos"
        cursor.execute(sql)
        result= cursor.fetchall()
        print(result)

        pdf= FPDF()
        pdf.add_page()

        page_width = pdf.w -2 * pdf.l_margin

        pdf.set_font('Times', 'B', 14.0)
        pdf.cell(page_width, 0.0, 'Productos 2022 Listado',align='C')
        pdf.ln(10)

        pdf.set_font('Courier', '', 12)
        col_width = page_width/4
        pdf.ln(1)

        th =pdf.font_size

        for row in result:
            pdf.cell(col_width, th, str(row['idProducto']), border=1)
            pdf.cell(col_width, th, row['name'], border=1)
            pdf.cell(col_width, th, row['precio'], border=1)
            pdf.cell(col_width, th, row['imagen'], border=1)
            pdf.ln(th)
        pdf.ln(10)

        pdf.set_font('Times', '', 10.0)
        pdf.cell(page_width, 0.0, '- fin del listado -',align='C')

        return Response(pdf.output(dest='S').encode('latin-1'), mimetype='application/pdf', headers={'Content-Disposition':'attachment;filename=productos_listado.pdf'})

    except Exception as e:
        print(e)

But I keep having this error message

'Connection' object is not callable"

I'm working with flask_mysqldb, (I've seen similiar errors but they've been working with MYSQLalchemy, not my case).
