Engine-API returns 500 on every request

When trying to fetch data from engine-api I get an error code 500 in the request. I does not matter which endpoint I use.

I noticed this while testing my latest changes in engine-core. If I check out this commit and build+start the container myself, everything works as intended.

Steps to Reproduce

Follow the installation steps for aura-playout
Only start engine-api and engine-api-postgres
Try to query any data, for example http://localhost:8008/api/v1/trackservice/current
Observe the response: status code 500
Set up a custom docker container with this commit
Build and start the container
Try to query any data
Observe the response status code 200

Expected Result

Meaningful data.

Actual Result

Internal server error 500.

The logs for the docker container engine-api do not show any error, the error is only logged in the file mentioned above.

Environment

local installation of the main branch from the aura repository
the tests with this commit were done by using the docker-compose.override.yml file and building the engine-api container myself.
