Container ignores DB_TYPE

Setup information Docker, deployed on Kubernetes using Custom Deployment

Describe the bug The container starts, but after a long time it crashes saying that the MySQL Server is gone while I set the environment variable to use Postgres. When I jump into the container, the Environment Variable shows:

~ $ echo $DB_TYPE
pgsql

Somehow this variable is being ignored.

To reproduce Steps to reproduce the behavior:

Deploy the invoice ninja container, set environment variables as described in the following.
Have a PostgreSQL running (14.x in my case)
Wait for the logs

Expected behavior It should connect to the postgres.

Additional context I execute it without root privileges - do I need to specify gid/uid? It at least doesnt show any privilege issues.
