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

FULL DISCUSSION
 

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.

 

for local development and testing:
npm run dev will run it has a next app without serverless (only pages are available, no serverless functionality written in server.js). You need to use serverless-offline github.com/dherault/serverless-off...

 

Same here. I'm getting the internal server error and the issue has to do with calling app.render. Further research leads me to believe that the problem stems from not calling app.prepare before configuring the server.

 

I get the same error when deploying the app to AWS.

Error:
{
message: "Internal server error"
}

The routes work fine locally, except the dynamic _breed route which results in a 404.

I've tried everything myself and also cloned the git repo as is to test. Both give the exact same result mentioned above. I have a custom domain linked via "sls create_domain" command.

 

I would add the same exact comment. I get Internal server error. If I try to add the /test get route, it works fine. If I try next locally it displays fine on localhost:3000. I myself has not even removed the customDomain section as I have a domain on Route 53 for that.

I have just tried copying the repo provided in the article and deploying it to my domain. Still the same Internal server error.
