Error write PIPE in AWS using buffer

Hey guys,

I having this error when i get the buffer of content of pdf and save in S3.

The error:

How i doing the generate PDF

let html = fs.readFileSync('contrato.html', 'utf8');

return new Promise((resolve, reject) => {
  pdf.create(html).toBuffer(async function(err, buffer) {
    const saveS3 = await salvaS3(buffer, dados.documento);

    if (saveS3.status !== 200) {
      resolve({
        status: 400,
        data: 'Erro'
      });
    }

    resolve({
      status: 200
    });
  });
});

Have you tried adding phantomPath?

pdf.create(html, {
  phantomPath: path.resolve(
    process.cwd(),
    "node_modules/phantomjs-prebuilt/bin/phantomjs"
  ),
})

So I believe that write EPIPE errors usually mean that the writing failed because the receiving end closed the connection. Which bit of your code is on line 53 in app.js?

Thank you. I’ve solved it. Your suggestion is valid only if phantomjs prebuild is installed; After the correct phantompath is configured, everything is normal; Although a “referenceerror: can’t find variable: $” error occurred later, I removed the script through regular expressions and everything went back to normal.

Hi, I think I’m having a very similar issue. I’m not an experienced dev, could you please share the steps you did to fix it¿?

This is my error, i’m using pdf-creator- node which uses phantom.js

events.js:292 throw er; // Unhandled ‘error’ event ^
