So I have this rather random error in NodeJS which is providing me no
information as to what is causing the error:
<code>
stream.js:81
throw er; // Unhandled stream error in pipe.
^
Error: write EPIPE
at errnoException (net.js:770:11)
at Object.afterWrite (net.js:594:19)
</code>
And this is the code that is causing the error:
<code>
var nodemailer = require('nodemailer');
var NewsletterEmail = require('./NewsletterEmail.js');
function NewsletterMailer(fromEmail)
{
this._from = fromEmail;
this._transport = nodemailer.createTransport('Sendmail');
}
NewsletterMailer.prototype = {
send: function(email, newsletterEmail, callback) {
var mailOptions = {
to: email,
from: this._from,
subject: newsletterEmail.getSubject(),
html: newsletterEmail.buildHTML(email),
text: newsletterEmail.buildText(email)
};
this._transport.sendMail(mailOptions, callback);
},
close: function() {
this._transport.close();
}
}
function Newsletter()
{
this._id = 1;
this.countSent = 0;
this.emailsToSend = ['[email protected]', '[email protected]',
'[email protected]', '[email protected]', '[email protected]',
'[email protected]'];
}
Newsletter.prototype.send = function() {
var newsletter = this;
var newsletterEmail = NewsletterEmail.create('folder', 'file');
var mailer = new NewsletterMailer('[email protected]');
function sendEmail() {
var email = newsletter.emailsToSend.pop();
mailer.send(email, newsletterEmail, function(mailerErr) {
if (mailerErr) {
console.log('Mailer error: ', mailerErr);
}
newsletter.countSent++;
console.log('progress ' + newsletter.countSent);
if (newsletter.emailsToSend.length > 0) {
sendEmail();
}
else {
mailer.close();
console.log('complete');
}
});
}
sendEmail();
}
var nl = new Newsletter();
nl.send();
</code>
When calling sendNew I will randomly get the EPIPE error at certain.
Anybody got any ideas or tips for debugging this problem? Anything would be
very much appreciated at this point.
The stack trace is fairly useless here and all the other solutions ive seen
have be todo with process spawning or the connect web framework.
