Getting blank email content in Pages Mailchannel middleware

Trying out the new MailChannel integration on Pages and I seem to be able to send an email from a form on my site, but when I receive the email it has no body content at all. I am not specifying the ‘content’ array for html/text versions so it should be using the default provided by the plugin as far as I can tell.

Here is the middleware code stored in /functions/_middleware.js (redacted for privacy)

import mailchannelsPlugin from '@cloudflare/pages-plugin-mailchannels'

export const onRequest = mailchannelsPlugin({
  from: { name: '#######', email: '[email protected]#########' },
  personalizations: [
    {
      to: [{ name: '#########', email: '#############' }],
    },
  ],
  respondWith: () =>
    new Response(null, {
      status: 302,
      headers: { Location: '/enquiries/thank-you' },
    }),
  subject: '######### Website Enquiry',
})

form (class attributes removed for brevity)

<form data-static-form-name="contact">
    <div>
        <div>
            <label for="first-name">First name</label>
            <input type="text" name="first-name" id="first-name" autocomplete="given-name"/>
        </div>

        <div>
            <label for="last-name">Last name</label>
            <input type="text" name="last-name" id="last-name" autocomplete="family-name"/>
        </div>

        <div>
            <label for="email-address">Email address</label>
            <input type="text" name="email-address" id="email-address" autocomplete="email"/>
        </div>

        <div>
            <label for="phone">Phone</label>
            <input type="text" name="phone" id="phone" autocomplete="phone"/>
        </div>
        <div>
            <label for="message">Message</label>
            <textarea id="message" name="message" rows="4"/>
        </div>
    </div>
    <div>
        <button type="submit">Send Enquiry</button>
    </div>
</form>

Any help would be appreciated.

I am having the exact same problem and my code looks very similar to yours. What’s even more bizarre is that mine was working a few weeks ago. My code hasn’t changed at all.
