Write EPIPE error when filling form using node-pdftk - pdftk

Question

I am trying to fill a pdf form using nodejs.
Im trying to use node-pdftk package for the same.Did following steps:
Installed pdftk for windows
mapped the path to the environment variables PATH
installed node-pdf package
`const express = require('express')
const app = express()
const cors = require('cors')
const pdftk = require('node-pdftk');
const bodyParser = require('body-parser');
var multer = require('multer'); // v1.0.5
var upload = multer();
app.listen(8000, () => {
console.log('Server started!')
});
var pdfPath='OoPdfFormExample.pdf';
app.use(bodyParser.json({limit: '50mb'}));
app.use(bodyParser.urlencoded({limit: '50mb', extended: true}));
var formdata = {
'Given Name': 'Swetha',
'Family Name': 'Gulapannavar'
}
app.post('/api/file', upload.array(), (req, res, next) => {
//var buffer=JSON.stringify(Buffer.from(req.body));
var buffer=Buffer.from(req.body)
pdftk
.input(pdfPath)
.fillForm(formdata)
.flatten()
.output()
.then(buffer => {
// Still returns a buffer
res.type('application/pdf'); // If you omit this line, file will
download
res.send(buf);
})
.catch(err => {
res.send(err.message)
// handle errors
});
});`
but i'm getting following error when i try to execute the same.
Write EPIPE error.

This could be caused by node-pdftk not being able to find the PDFtk binaries; your PATH variable may not be set correctly for the account running your web service. You can set the bin path directly inside of your application using node-pdftk's configure function, which is briefly described on the node-pdftk npm project page. If that doesn't work, try configuring the tempDir path.
