Discussion on: A crash course on serverless-side rendering with React.js, Next.js and AWS Lambda

Great tutorial - thank you! I finished the tutorial and successfully deployed, but am getting errors when navigating to the site. When navigating to https://[unique id].execute-api.us-east-1.amazonaws.com/dev/, I get the message {"message": "Internal server error"}. One nuance is that I removed the customDomain section, as I was hoping to use the AWS endpoint.

One thing I did when testing, is I added "dev": "next" to the scripts object in the package.json, so when I run npm run dev, I get the correct information displaying at localhost:3000, localhost:3000/dogs, etc.

Also, I added the code below to the server.js file, and when I navigate to https://[unique id].execute-api.us-east-1.amazonaws.com/dev/test, I get the 'Hello World!' message displaying, as expected:

server.get('/test', (req, res) => {
res.send('Hello World!');
});

The full server.js file is below. The server.get function with the res.send works, but the server.get functions with the app.render always throw an error.

const express = require('express');
const path = require('path');
const dev = process.env.NODE_ENV !== 'production';
const next = require('next');
const pathMatch = require('path-match');
const app = next({ dev });
const handle = app.getRequestHandler();
const { parse } = require('url');

const server = express();
const route = pathMatch();
server.use('/next', express.static(path.join(_dirname, '.next')));
server.get('/test', (req, res) => {
res.send('Hello World!');
});
server.get('/', (req, res) => {
app.render(req, res, '/')
});
server.get('/dogs', (req, res) => {
app.render(req, res, '/dogs')
});
server.get('/dogs/:breed', (req, res) => {
const params = route('/dogs/:breed')(parse(req.url).pathname)
return app.render(req, res, '/dogs/_breed', params)
});
server.get('*', (req, res) => handle(req, res))

module.exports = server;

Any insight would be greatly appreciated! Let me know if I can provide any additional information. Sorry if I'm doing anything real obvious, as I am completely new to Next.js and still fairly beginner with AWS.
