Error: write EPIPE
I'm using nunjucks to render a template into a string, i then try to convert that html to a pdf file however everytime i get this error:
Error: write EPIPE
at errnoException (net.js:905:11)
at Object.afterWrite (net.js:721:19)
Here is the code i use to create the pdf file:
nunjucks.render(path.join(__dirname, '../views/mail/receipt.html'), {
__: res.__,
query: req.query,
payment: payment
}, function(err, html) {
if (err) {
next(err);
}
htmlPdf.create(html, {
type: 'pdf'
}).toBuffer(function(erro, fileBuffer) {
// Code never gets this far, errors out before it happens and the error object is still null.
if (erro) {
next(erro);
}
var transporter = nodemailer.createTransport({
host: config.email.host,
port: config.email.port,
secure: config.email.secure
});
transporter.sendMail({
from: config.email.from,
to: payment.receipt_email,
subject: res.__({
phrase: 'Receipt_Email_Subject',
locale: payment.lang
}),
attachments: [{
filename: 'receipt.pdf',
content: fileBuffer,
contentType: 'application/pdf'
}],
text: 'test'
}, function(error, info) {
if (error) {
next(error);
}
res.json(info);
});
});
});
Here is the HTML string that is generated by nunjucks, not the most readable i know but figured i should post it like it is instead of trying to make it prettier

I've been stuck at this for hours and can't see that im doing anything wrong, any ideas?
I didn't have a look at your html yet, but there are some errors that don't get catched in your code. You're always using next like this.
function(err, html) {
if (err) {
next(err);
}
//...
}
In a case of an error, your code continues with the execution. To prevent this, you have to return the error like here:
function(err, html) {
if (err) {
return next(err);
}
//...
}
Have same issue.
html=Twig.twig({data: html}).render({
bodys: config.list.map(function(item){
return input.row[item.id].body;
})
});
var options = { filename: dest, format: 'Letter'};
console.log('Create pdf..');//Last console log before error
pdf.create(html, options).toFile(function(err, res){
if(err){
console.error(err);
callback(err);
}
console.log('Pdf file:',res.filename);
callback(err, dest_file);
});
This code working on my local machine (Win8), but on server (Debian) I got this error and server fault..
events.js:85
throw er; // Unhandled 'error' event
Error: write EPIPE
at exports._errnoException (util.js:746:11)
at WriteWrap.afterWrite (net.js:775:14)
I check path to file, its like this:
local: c:...path_to_project..\engine../public/reports/..filename.pdf server: /var/...path_to_project../engine/../public/reports/..filename.pdf
Paths like this works correctly in another places (generate images) What i can do with this problem? Have no idea..
UPDATE: solved my issue after a reboot. Yep, you read that right. :gun:
I don't know if the error is the same, but it surely looks very related to how the interaction with phantomjs is made: I am spawning my Node process (that uses node-html-pdf) from a C# application, and it looks like child.stdin.write fails with EPIPE.

at child_process.js:1144:20

The child process is of course phantomjs, and it crashes here (I am using version 2.0.0):
return child.stdin.write(JSON.stringify({
html: this.html,
options: this.options
}) + '\n', 'utf8');
My setup is Windows 8.1 x64, Node 0.12.7 and phantomjs 2.0.0 (manually installed, not via npm).
For reference, here's my C# code I am using to launch the PDF generation:
var process = new Process {
StartInfo = new ProcessStartInfo {
FileName = "myapp",
UseShellExecute = false,
RedirectStandardInput = true,
RedirectStandardOutput = true,
RedirectStandardError = true
}
};
try {
process.Start();
// write the JSON report to the standard input
process.StandardInput.WriteLine(jsonReport);
process.StandardInput.Close();
// wait for exit
process.WaitForExit();
if (process.ExitCode != 0) {
// THIS IS WHERE IT ERRORS
Console.WriteLine(@"{0}", process.StandardError.ReadToEnd());
}
Console.WriteLine(@"stdout: {0}", process.StandardOutput.ReadToEnd());
} catch (Exception ex) {
Console.WriteLine(ex.StackTrace);
}
Do you have any idea of what could cause the issue?
I had the same error
Error: write EPIPE
at errnoException (net.js:905:11)
at Object.afterWrite (net.js:721:19)
followed by this one
Error creating pdf [Error: /opt/app_name/app/programs/server/npm/npm-container/node_modules/html-pdf/node_modules/phantomjs/lib/phantom/bin/phantomjs: 4: /opt/app_name/app/programs/server/npm/npm-container/node_modules/html-pdf/node_modules/phantomjs/lib/phantom/bin/phantomjs: Syntax error: Unterminated quoted string
It is caused by phantomjs's executable being of a wrong architecture. If you have this error you can use this to check if the binary matches your system.
$ file /path/phantomjs
Running npm install on html-pdf should fix this.
same problem and running npm instal on html-pdf doesn't fix it.. anyone have found how to solve this ?
Not sure if this helps but I started encountering this exact same EPIPE issue while attempting to troubleshoot my rendering issue.
It was recommended elsewhere to add the following lines to the options but doing so is what causes the EPIPE issue for me. Removing these lines resolves the EPIPE issue.
"phantomPath": "./node_modules/phantomjs/bin/phantomjs", "phantomArgs": [],
sudo apt-get install libfontconfig fixed it for me, thanks @sovanna!
Hi marc
I am facing the EPIPE error once i have deployed my app to Amazon EC2 (Ubuntu 14.04.3 LTS). This works totally fine on my dev box, which is running Windows 10.
My app is a meteor app and it is deployed to EC2 using mupx.
I used to get the EOENT error and following the instructions here and other places, i did execute sudo apt-get install libfontconfig and after that the error changed to EPIPE
Here are my config options
pdfConfigOptions = {"directory": "/opt/<appname>/tmp",
"format": "A4",
"orientation": "portrait",
"border": "0",
"type": "pdf",
"quality": "75"
"timeout": 30000}
Here is my code invoking the pdf creation. (I removed the code that deals with the returned buffer as part of debugging)
var pdfCreator = Meteor.npmRequire('html-pdf');
let pdf = pdfCreator.create(html, this.pdfConfigOptions);
pdf.toBuffer(function (err, buffer) { //This line fails with the following error
});
events.js:72
throw er; // Unhandled 'error'event ^
Error: write EPIPE
at errnoException(net.js:905:11) at Object.afterWrite (net.js:721:19)
FYI: My code had Meteor.bindEnvironment around the callback function, but i removed that while testing to figure out what is causing these errors. This clearly is happening while html-pdf is trying to create the pdf using phantom,
phantom is installed on the image, See below
ubuntu@ip-<0.0.0.0>/opt/
Any help in pointing me to the right direction to either fix this or identify the issue is greatly appreciated.
Thanks a lot in advance for your time S
I was facing same EPIPE issue while generating pdf
@sovanna's "sudo apt-get install libfontconfig" worked for me
Thanks Buddy
I was getting following error while exporting pdf on my centOS system.
Error: write EPIPE at errnoException (net.js:905:11) at Object.afterWrite (net.js:721:19)
After running yum install fontconfig , now pdf is generating but its content is not visible. It is a simple html table.
Same case is working on my ubuntu system.
@bansalritesh18
Try adding the following via yum
freetype*
fontconfig
urw-fonts
I have the above 3 in my Dockerfile that I'm using with this module. These seemed to resolve my issues with fonts or styling.
I was getting the EPIPE error as well with an app running in docker containers on ec2s. In my case, it turned out not to be the fontconfig lib, but rather needing to npm rebuild phantomjs-prebuilt in my Dockerfile.
I had the same thing as @kevinbror and got it working by rebuilding phantomjs. (Everything worked fine in my macbook, but when I cloned the my git to Ubuntu, running my node server there was resulting the EPIPE error.)
are you pushing your node_modules to git?
Don't do that. All the platform specific modules won't work unless you run npm rebuild.
I am not that novice :-) My 'base project' is templated by swagger-node-express and it's default .gitignore keeps node modules out of git among other artefact files. However, I might have had a really old phantom version on my ubuntu machine from some other project I have been doing previously with angular app's test automation. But I have seen people's repos with node_modules as well as other library stuff so that is a valid concern you raised 👍
I had this problem in Docker as well, I was binding the source code into the container as a volume (for easy development). The problem was that I had built the original npm packages on the host and mapped them into the container (it seems that even npm didn't rebuild the needed packages for the container).
The solution was similar to @kevinbror except I had to rebuild everything from inside the container with $ npm rebuild
I am having the same issue on macOS

at WriteWrap.afterWrite [as oncomplete] (net.js:804:14) code: 'EPIPE', errno: 'EPIPE', syscall: 'write' }
tried every possible solution suggested on web. doesn't got any luck. any suggestions ?
And when i try to convert the HTML from terminal it works fine. :(
You just have to install libfontconfig1package.
For debian users: sudo apt-get install libfontconfig1
Hi, I am using html-pdf npm package for my electron app. It was working perfect in both development and production environment. But now after using ASAR to pack my code, it stopped working in production. Gives Error

The solution mentioned by others i.e. to install libfontconfig is not applicable here since there is not libfontconfig package in npm.
Being a nube I expect to be clarified if i failed to understand things from the error msg or from the above discussions.
P.S: I am well aware that ASAR pack are read only. So the path for pdf is outside it. But still the same problem. Does html-pdf perform any write operation other then the final write to the file path specified?
@ishwarrimal any chance you figured out a solution to this issue with electron? Dealing with this now...
hi @danmckeon, since html-pdf package was doing some write operation internally, the only solution for me was moving out this package from node-modules and keeping it one level outside the current directory and giving the absolute path. But with that included, the installer size was getting huge.
Hence later i found out that electron on itself has provide a tool for printing pdf. So using that it was very easy for me.
I would prefer the second approach (using inbuilt tool) but if you want to know more about the first approach please let me know.
Hope this helps.
@ishwarrimal I noticed that tool, but every PDF I create with Chromium (including with the Electron tool) is huge. Did you find a workaround for that?
I have the same problem on Windows and cant get html-pdf to work after packing to asar. Anyone found a workaround on this issue?

The problem is on Linux OS You can use fc-list first to check if there is a font library installed
If the instruction is invalid, you can install the font according to the version
Ubuntu / Debian sudo apt-get install libfontconfig
Centos / Redhat sudo yum install fontconfig
