Error write PIPE in AWS using buffer

[MatheusLuiz2000]

Hey guys,

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

The error:

errors: {error: {message: "write EPIPE", name: "Error",…}}
error: {message: "write EPIPE", name: "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
    });
  });
});

You could use toStream() instead.

Example:

pdf.create(html).toStream((error, stream) => {
    stream.pipe(() => {
        let pass = new stream.PassThrough();
        s3.upload({
            Bucket: "",
            Key: "",
            ContentType: "application/pdf",
            Body: pass
        }, (error, data) => {
            // Finished uploading or error
        });
        return pass;
    });
});

Have you tried adding phantomPath?

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

您是否尝试过添加 ？phantomPath

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

ReferenceError: path is not defined, What's the path here?

[ghost]

@Jiale-Li path is a node module. You will need to require it like so:

const path = require('path')

In your code what the resolve method does is basically combines your current working directory and the path for phantomjs into an absolute path.

Ah, thank you. I see, but it didn't work. I tried to convert HTML directly to PDF, Error reporting looks like a problem with the pipeline, I should learn something about it.

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?

I found that I did not install phantomjs prebuild and am trying to install it now

pdf.create(html, options).toFile('./tmp/test.pdf', (err, data) => {
        if (err) {
            res.send({
                code: 1,
                msg: 'err！'
            })
        } else {
            res.sendFile(data)
        }
});

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.

Glad to hear you got it working! :)

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
