Hi! I'm new here, and I've set up a laravel12 application, but some pages within the application get error 502... but only here, when I test in my local environment, it works normally... I don't know what I can do. And I don't get anything in the logs, and my application is fine and works normally on other pages. But some specific, small actions give rise to errors.

In my log the only thing that appears is this:

2025/05/14 13:17:57 [error] 36#36: *79 upstream sent too big header while reading response header from upstream, client: 100.64.0.5, server: localhost, request: "GET /sales HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "pdv-system-production.up.railway.app"

I think it might be something with nginx, but could I configure nginx here? What can I do to avoid this? In my code everything looks normal... so much so that it works in other environments.
