[master tag] 500 error while doing API request with invalid json

[saw-jan]

⚠️ use master image tag

Steps to reproduce:

1. run Nextcloud:

   docker run --rm -e SERVER_BRANCH=stable33 -e NEXTCLOUD_AUTOINSTALL=true -p 8080:80 ghcr.io/juliusknorr/nextcloud-dev-php83:master

2. enable integration_openproject app

3. request with invalid json:

   curl -XPOST 'http://localhost:8080/index.php/apps/integration_openproject/setup' -u admin:admin -d'{"values:}' -H'Content-Type: application/json'

   500 Internal Server Error
   {some html}

I also tried to get the methods execution order using logs and the logs order is wrong:

👉 But the same works with local setup and old ghcr.io/juliusknorr/nextcloud-dev-php83:20231202-1 image tag
I get expected 400 error ✔️
For this working scenarios, the logs order is correct
