Help: TypeError: Cannot read property 'passport' of undefined on production build

Bug report

Describe the bug

Everything runs fine on development. The issue happens on production.

‘npm run build’ executes without issues, but once I ‘npm run start’ and visit the page (localhost:3000), I get an “Internal Server Error” on the DOM and my terminal says “TypeError: Cannot read property ‘passport’ of undefined”.

The terminal is pretty much pointing at this being the issue inside _app.js:

    if (ctx.req && ctx.req.session.passport.user) {
      pageProps.user = ctx.req.session.passport.user;
    }

To Reproduce

Steps to reproduce the behavior, please provide code snippets or a repository:

I have config and .env file’s required to connect to auth0 and my personal DB, so this may not work. Maybe someone can still help?

1. Go to My project’s repo: https://github.com/apardo04/stock-market-react-app
2. clone it
3. npm install and go to directory
4. npm run build
5. npm run start
6. Go to localhost:3000
7. See error

Expected behavior

Site runs with no issues

Screenshots

OK, so to fix this new issue I had to run:

"start2": "cross-env NODE_ENV=production node server.js"

instead of:

"start": "next start -p 3000",

This allowed me to go to /login and work normally.

@apardo04 After cloning your project and trying to reproduce the bug, I think that the problem might come from the session object not being available on the req.

If you add another check to the if statement you’ve linked, like the line below, it works: ctx.req && ctx.req.session && ctx.req.session.passport

Does anyone have another thought?
