NullpointerException in TopicRepository.list #32

When I start the app with

docker run \
    -p 8080:8080 \
    -v /tmp/application.conf:/app/application.conf \
    tchiotludo/kafkahq:0.4.1

I get the following error:

My application.conf being

{
  kafka {
    connections {
      plaintext {
        bootstrap.servers: "kafka:9092"
      }
    }
  }
}

The configuration files have changed to yml or json. Also changed the the prefix from kafka to kafkahq Take a look at this : https://github.com/tchiotludo/kafkahq#configuration

should be : 

kafkahq:
  connections:
    plaintext:
      properties:
        bootstrap.servers: "kafka:9092"
