Troubleshooting Email Communication Errors: A Persistent Challenge

I am new to nodemailer and trying to work on a simple application. However, I keep encountering errors within the nodemailer module when running my app.

Here is my app.js code:

const nodemailer = require('nodemailer');

const transporter = nodemailer.createTransport('smtps://me%40gmail.com:<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="700305001502031513021504000730031d04005e171d11191c5e131f1d">[email protected]</a>');


var mailOptions = {
    from:    '"Me" <<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="711c1431161c10181d5f121e1c">[email protected]</a>>', // sender address
    to:      '<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="721a1b1f321a1b1f5c111d1f">[email protected]</a>, <a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="fc94998ebc94998ed29f9391">[email protected]</a>', // list of receivers
    subject: 'Hello dude', // Subject line
    text:    'Test email with text', // plaintext body
    html:    "Testing 1..2..7" // html body
};

// send mail with defined transport object
transporter.sendMail(mailOptions, function (error, info) {
    if (error) {
        return console.log(error);
    }
    console.log('Message sent: ' + info.response);
});

The error message I receive is as follows:

C:\Users\Andrew\desktop\messy4\node_modules\nodemailer\lib\mailer\index.js:31
            compile: [(...args) => this._convertDataImages(...args)],

I am unsure about what could be causing this issue.

Answer №1

To run this program, you must have Node.js version 6 or higher installed on your system. To check your current Node.js version, enter the following command:

node --version

If your Node.js version is below 6, you will need to upgrade in order to proceed.

If you encounter an error prompting you to log in to your account, simply check your email inbox for a message from Google containing a link to set up permissions for less secure apps.

Answer №2

To easily specify the Node.js version in your project, insert the following code snippet into your package.json file:

"engines": {
    "node": "12.18.4"  // Feel free to choose another version
  }

With this configuration, Node.js will automatically be installed with the specified version upon installation. This eliminates the need for manual NodeJS updates on your server.

Answer №3

Nodemailer functions properly with Node version 6 or higher (according to )

Here are the steps to update your node version:

1* sudo npm cache clean -f

2* sudo npm install -g n

3* sudo n stable

4* sudo ln -sf /usr/local/n/versions/node/5.4.1/bin/node /usr/bin/node (the bold text/version should reflect the one installed in the previous step.)

For example, if version 8.1.1 is installed, then run sudo ln -sf /usr/local/n/versions/node/8.1.1/bin/node /usr/bin/node

node –v (It should now display the updated version)
