Netlify function - event.body is always empty

Hello,

Im trying to send email with netlify function and Mailgun, i create a function :

require('dotenv').config()
const { MAILGUN_API_KEY, MAILGUN_DOMAIN, MAILGUN_URL, FROM_EMAIL_ADDRESS, CONTACT_TO_EMAIL_ADDRESS } = process.env
const mailgun = require('mailgun-js')({ apiKey: MAILGUN_API_KEY, domain: MAILGUN_DOMAIN, url: MAILGUN_URL })

exports.handler = async(event) => {

    if (event.httpMethod !== 'POST') {
        return { statusCode: 405, body: 'Method Not Allowed', headers: { 'Allow': 'POST' } }
    }

    const data = JSON.parse(event.body)

    console.log(data)

    if (!data.message || !data.contactName || !data.contactEmail) {
        return { statusCode: 422, body: 'Name, email, and message are required.' }
    }

    const mailgunData = {
        from: FROM_EMAIL_ADDRESS,
        to: CONTACT_TO_EMAIL_ADDRESS,
        'h:Reply-To': data.contactEmail,
        subject: `New contact from ${data.contactName}`,
        text: `Name: ${data.contactName}\nEmail: ${data.contactEmail}\nMessage: ${data.message}`
    }

    return mailgun.messages().send(mailgunData).then(() => ({
        statusCode: 200,
        body: "Your message was sent successfully! We'll be in touch."
    })).catch(error => ({
        statusCode: 422,
        body: `Error: ${error}`
    }))
}

When i invoke it with :

netlify functions:invoke send-contact-email --port 8888 --no-identity --payload '{"foo":1}'

I always get an empty body from my console.log(data) :

Request from ::ffff:127.0.0.1: POST /.netlify/functions/send-contact-email
{}

Anyone can try to help me ?

Hey @Tonyweb

I have a function called splat in which I added the line

console.log(event.body)

I then ran

ntl functions:invoke splat --payload '{"foo":1}'

And saw

Request from ::ffff:127.0.0.1: POST /.netlify/functions/splat
{"foo":1}

Thanks for your reply but i can’t get the same results, more informations below :

  • I’m using nuxt3

Maybe this can help ?

I don’t believe that should matter. As long as the function is available.

This is what I am using.

When I console.log(event) I see the body data as well. Given the console.log is showing something, it means the function is invoked.

Did you try without the extra flags as per the command I used?
Have you tried another (basic function) to test?
Have you tried an alternate method such as cURL?

This is the function I used:

exports.handler = async(event) => {
  console.log(event)
  return {
    statusCode: 200,
    body: "OK"
  }
}
