Sveltekit + Cloudflare Pages + Resend

Hello! I've been banging my head against a wall as i don't know how to go about finding out whats wrong: I've written a server.js file with a POST that when called sends and email out. It works in local development but once i commit to the git repository and it is deployed on cloudflare pages when i click the button to test send the mail, the console logs a

'{message: 'Internal Error'}message: "Internal Error"[[Prototype]]: Object'

'{message: 'Internal Error'}message: "Internal Error"[[Prototype]]: Object'

along with a

'status code: 500'

'status code: 500'

In addition, i'm using 'svelte-email' which is a port of 'react-email' for sveltekit. Could the problem be there? +server.js

import { json } from '@sveltejs/kit'; 
import { render } from 'svelte-email';
import { Resend } from 'resend';
import { RESEND_API_KEY } from '$env/static/private';
import MailTemplate from './MailTemplate.svelte';

const resend = new Resend( RESEND_API_KEY );

export const POST = async ({request}) => {
    const body = await request.json()
    console.log(body);

    const {invoiceEmail,invoiceCustomer,invoice} = body;

    const html = render({
        template: MailTemplate,
        props: {
            firstName: invoiceCustomer,
            invoiceEmail: invoiceEmail,
            invoiceCustomer: invoiceCustomer,
            invoice:invoice
        }
    })

    try {
        resend.emails.send({
            from: 'Notifications FOS <[email protected]>',
            to: invoiceEmail,
            subject: 'Hello '+ invoiceCustomer,
            html: html
        });
        console.log('Email sent successfully');
    } catch (error) {
        console.log('There was an error sending the mail',error);
    }


    return json({status:201,message: 'Email sent'})
}

import { json } from '@sveltejs/kit'; 
import { render } from 'svelte-email';
import { Resend } from 'resend';
import { RESEND_API_KEY } from '$env/static/private';
import MailTemplate from './MailTemplate.svelte';

const resend = new Resend( RESEND_API_KEY );

export const POST = async ({request}) => {
    const body = await request.json()
    console.log(body);

    const {invoiceEmail,invoiceCustomer,invoice} = body;

    const html = render({
        template: MailTemplate,
        props: {
            firstName: invoiceCustomer,
            invoiceEmail: invoiceEmail,
            invoiceCustomer: invoiceCustomer,
            invoice:invoice
        }
    })

    try {
        resend.emails.send({
            from: 'Notifications FOS <[email protected]>',
            to: invoiceEmail,
            subject: 'Hello '+ invoiceCustomer,
            html: html
        });
        console.log('Email sent successfully');
    } catch (error) {
        console.log('There was an error sending the mail',error);
    }


    return json({status:201,message: 'Email sent'})
}

I'm not sure how i can debug this as from the cloudflare pages function tab i get a 500 saying process is not defined. Any ideas?

I’m not seeing immediately what api svelte-email uses for requests but I suspect it’s the node api. Workers only support web APIs, like a browser. You can’t use http.get or axios. You may be able to configure svelte-email to use fetch(). I had a similar problem with postmark. Solution for me was https://blog.cloudflare.com/sending-email-from-workers-with-mailchannels/
