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.
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.
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.
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.
Hi, this raised a couple a questions with me:
serverless
provide in this scenario? What are the alternatives(aws cli?terraform?idk.)?Hey, glad to answer.
Hope this answers your questions. Feel free to let me know if you have any more. :D
This was the error I received after I ran 'npm run deploy' for the first time.
I have a domain name that ends in .info
Could that be the cause?
Hi,
Once I deploy this, I'm able to load the front page, but all the next resources (*.js) come back as 403, any idea why?
Thanks for your help,
FWIW, you're probably seeing issue from not deploying with custom domain and needing to have the stage in the path to access the resource, e.g.
https://XXXXX.execute-api.us-east-1.amazonaws.com/production/_next/static/YYYYY/pages/index.js
is needed buthttps://XXXXX.execute-api.us-east-1.amazonaws.com/_next/static/YYYYY/pages/index.js
is what the express response actually renders.This explains some of issue and attempts to make it work github.com/dougmoscrop/serverless-...
as well as this: github.com/zeit/next.js/issues/6447
Can you try cloning the repo and deploying it? If that works, there has to be a strange issue somewhere in your code. Compare your project to the cloned repo. Hopefully, that'll help you out. :)
It doesn't work when I clone it from the repo either. The only thing I've changed were the values in secret.json
On local routes work fine, except for the dynamic "_breed" route. It results in 404 Not Found.
On deploying to AWS all routes result in message: "Internal server error" ... you can check it out at ecom.ideamappers.com
That does not work. It gives and internal server error as soon as you try using app.render.
Hi,
I have exactly the same issue.
Where you able to solve it?
Thanks
I have stumbled on a few of your tutorials Adnan and they are all awesome. I actually read through all of this before realising it was you (I got into Serverless when I read your Express, Mongo + Serverless tutorial on hackernoon). NextJS is great and I am stoked that it is just as easy to deploy to Lambda. Thank you!
Hey Gary! Wow, thanks for the kind words. I'm glad I can help the community understand serverless architectures. Stay tuned for more tutorials. :)
Have you done any performance testing on this setup? I would be interested to know some numbers like TTFB and others.
I haven't actually. I'd be stoked to know the performance too. Once I find the time, I'll surely check it out. If you get around to doing it yourself, please let me know! :D
I saw that Next.js 8 was released after you published this article. It has a section about how serverless is now supported. Should I do anything differently because of this?
Hey, this is great thanks! For those following the tutorial and copying and pasting the code, there is a typo in index.js.. it is missing

. FYIOh wow, nice catch! Thanks for that. I've gone in and fixed the typo. I'm glad you like the tutorial. :)
Is it possible to display images from the static folder once the site is deployed? I added an image for a logo to the static folder and am displaying it in the header component. It shows while I'm developing on localhost, but when I deploy to AWS it shows as a broken image.
Here's my code:
github.com/joshglazer/freetimeupda...
I figured this out myself. In case anyone's curious, you can fix this by adding the following line of code to your server.js file.
server.use('/static', express.static('static'))
Great tutorial - thanks alot! I am new to the NextJS x AWS Lambda stack. When I call the function url, all I get is a random string like: PCFET0NUWVBFIGh0bWw+CjxodG1sIGxhbmc9ImVuIj4KPGhlYWQ+CjxtZXRhIGNoYXJzZXQ9InV0Zi04Ij4KPHRpdGxlPkVycm9yPC90aXRsZT4KPC9oZWFkPgo8Ym9keT4KPHByZT5DYW5ub3QgR0VUIC88L3ByZT4KPC9ib2R5Pgo8L2h0bWw+Cg==
Locally everything works fine and I can see that NextJS is rendering my pages. However, on lambda all I get is that random string.
Do you know why this could be happening? Thanks alot :D
So you keep the secrets file locally? What if you are on a team and want to deploy this through CI/CD? Would you handle that on there?
You use AWS KMS. Here's a nice Serverless plugin. :)

Serverless KMS Secrets
A Serverless Plugin for the Serverless Framework which helps with encrypting service secrets using the AWS Key Management Service (KMS)
Introduction
This plugins does the following:
Installation and configuration
In your service root, run:
Add the plugin to

:Configure the plugin into the custom block in
