Please take a look at what is sent here.
The first argument should be a path to the phantomjs. Is it properly installed?

I used like this

const htmlPDF = require('phantom-html-to-pdf')({
'numberOfWorkers': 2,
'tmpDir': TEMP_DIR,
'strategy': "dedicated-process",
'phantomPath': require('phantomjs-prebuilt').path
});

As per node https://www.npmjs.com/package/phantomjs is renamed to phantom-prebuilt . So i used the phantom prebuilt.

htmlPDF({ html}, ( error, pdf ) => {
if ( error ) {
reject({'message': Unable to create file ${fileName}, error});
}
else {
const {
path: tmpPath
} = pdf.stream;

   const fileStream = fs.createWriteStream(fileName);
   pdf.stream.pipe(fileStream);

}})

Please help me what is wrong in my code

Based on the error require('phantomjs-prebuilt').path is not producing valid path.
Try to debug it.
