"missing required error components, refreshing..." when building in production

[DanielPantle]

Summary

Hello together,

I am trying to upgrade my next.js app from version 12 to 13. I use a webhosting provider with plesk and I use TailwindCSS in my application.

When building the app in production and starting it, I get the following error when accessing the page:
missing required error components, refreshing...
In the console, the following network error is logged approx. every second:
XHRGET https://.../ [HTTP/1.1 500 Internal Server Error 46ms]
The reply contains the error text from above.

As a start file, I tested node_modules/.bin/next and node_modules\next\dist\bin\next. For next.js 12, only the first one worked.

When building the app with development environment, everything works fine.

Did you figure out a solution?

For me, this was caused by using & instead of && in one of my scripts inside package.json. As a result, I somehow ended up running multiple next servers at the same time (?).

I used & intentionally to run a script in the background, but apparently this won't work.

a single & means that the preceding commands—to the immediate left of the &—should simply be run in the background.

Right. I tried to run next dev in the background to execute some other scripts along with npm run dev, but as you're probably implying, the server process doesn't stop as expected then.

Lifesaver. I was going bananas until reading this and I realized I had two terminals running next dev
