7 months ago I have same issue. And I found the server.js which compiled with standalone can works. So I just copy these 2lines, and my custom server.js also works fine.
const nextConfig = {which from compiled server.js}
process.env.__NEXT_PRIVATE_STANDALONE_CONFIG = JSON.stringify(nextConfig)

7 months ago Here's my code, and while it works successfully, I'm not sure it's going to be a hidden problem
import { createServer } from 'node:http';
import { parse } from 'node:url';
import NextServer from 'next/dist/server/next-server';
// @ts-ignore
import { config } from './.next/required-server-files.json';
import { NextConfig } from 'next';
const port = parseInt(process.env.PORT || '9000', 10);
const hostname = '0.0.0.0';
const dev = process.env.NODE_ENV !== 'production';
const app = new NextServer({
hostname: 'localhost',
port,
dir: process.cwd(),
dev,
conf: {
...(config as NextConfig),
},
});
const handle = app.getRequestHandler();
app.prepare().then(() => {
createServer((req, res) => {
try {
const parsedUrl = parse(req.url!, true);
handle(req, res, parsedUrl);
} catch (err) {
console.error('Error occurred handling', req.url, err);
res.statusCode = 500;
res.end('internal server error');
}
})
.once('error', (err) => {
logger.error(err);
process.exit(1);
})
.listen(port, () => {
console.log(
`> Server listening at http://${hostname}:${port} as ${
dev ? 'development' : process.env.NODE_ENV
}`,
);
});
});

4 months ago I confirmed that this works for me: https://github.com/vercel/next.js/issues/64031#issuecomment-2078708340
So AWS lambda, I am using the following to extract the JSON:
sed -n 12p .next/standalone/server.js | cut -c 20-
then require it inside my lambda handler file.
If I had more time I will figure out which particular parameter in the config made it work by commenting them out one at a time.

Thanks @nectoscorp
After I tested, it works 😂

4 months ago I wish the nextConfig json was just saved on a file in like .next/standalone/next.config.json so we don't have to resort to these hacks. But obviously, the best is solution is to find out why bundle5 couldn't be found.

2 months ago Having the same issue. This seems to work well for me to allow for both local dev development and docker deployment:
const dev = process.env.NODE_ENV !== 'production'
if (!dev) {
// eslint-disable-next-line @typescript-eslint/no-require-imports
const { config } = require('./.next/required-server-files.json')
process.env.__NEXT_PRIVATE_STANDALONE_CONFIG = JSON.stringify(config)
}

The ES6-conform version:
import("./.next/required-server-files.json")
.then(({ default: { config } }) => {
process.env.__NEXT_PRIVATE_STANDALONE_CONFIG = JSON.stringify(config);
const app = next({ dev });
return app.prepare().then(() => startServer(app) // startup func);
})
.catch((error) => {
console.error("Failed to load required-server-files.json:", error);
process.exit(1);
});

2 months ago I have the same issue but surprisingly in PM2 as local & VM's was working fine
Can anyone summarize why this issue is ??
/** @type {import('next').NextConfig} */
const nextConfig = {
output: 'standalone',
typescript: {
ignoreBuildErrors: true
},
images: { unoptimized: true },
experimental: {
serverActions: {
serverActions: true
},
missingSuspenseWithCSRBailout: false
},
distDir: 'out',
rewrites: async () => {
return [
{
source: '/_next/static/:path*',
destination: '/static/:path*'
}
];
}
};
export default nextConfig;

1 month ago I found a universal way if adding missing dependencies to standalone output that I guess can also be used for custom server.

1 week ago I also ran into this issue and came up with the exact same fix
I put up a PR to fix this in next.js: https://github.com/vercel/next.js/pull/72966
Link to the code that reproduces this issue
https://github.com/maximelebastard/nextjs-issue-custom-server
To Reproduce
The issue is related to using the output: "standalone" with a custom server. See example repository.
npm installthennpm run buildandnpm run startCurrent vs. Expected behavior
Expected:
output: "standalone"configuration innext.config.jsserver.jsnpm run buildand copy my custom server code to the build dir, the app is properly built and the file is properly copiedserver.js, all the dependencies are present and the server startsActual:
.next/standalone/node_modules/next/dist/compiled/webpack/build5.jsdoes not exists in the built appserver.js, I'm getting the error below because webpack tries to requirebuild5.jsProvide environment information
Which area(s) are affected? (Select all that apply)
Standalone mode (output: "standalone")
Which stage(s) are affected? (Select all that apply)
next start (local)
Additional context
A workaround I found is to disable standalone output. That probably disables tree shaking and relies on the complete node_modules directory. A big drawback is that it makes a heavy docker image.
