HTTP Error 500

[JK-Effects]

Hi
I have installed the typo3 image version 12 via my docker compose.
The communication to the installation of typo 3 through traefik works according to the console.
There I get a response per browser call with the call from the browser.

However, the browser only receives an error 500 in response.
This also prevents me from completing the installation-process of the typo3 instance.

What could be the reason that only an error 500 is returned?

Did you find a solution for this?
I was able to deploy it in production a few weeks ago, now my team needs a container for dev too and I can't deploy it, no matter what I change.

I haven't found any solution yet.
But if I do find anything that works, I'll post it here.

Maybe someone else does know what to do, to fix that error.
