bug: docker-compose not working, also error handling issue, as it returns empty JSON.

[aea7]

Error Description

docker-compose not working for several reasons:

• kafka not accessible
• postgres port is wrong since consumer and api need 5432 to access postgres
• kafka_ui could not connect to kafka
• consumer and api were failing to connect to kafka, so consumer panics.

There's a clear error handling issue, as it returns empty JSON instead of error message or meaningful information.

Reason: marshalling error interface will result in {"err": {}}

Error Environment

Local Development

Describe how you got the error step by step

1. run docker compose up
2. The api does not run, after correction, I was calling the needs endpoint and it was returning empty JSON as a response, when I checked the db, nothing was inserted.

Expected Behaviour

Api issues and the local development with docker compose to be fixed, along with error handling.

Screenshots

If applicable, add screenshots to better illustrate the problem.

Desktop Environment

Docker compose is only for local development. Users should arrange the port according to their local ports.
