Kafka manager no application loader is configured - docker

Question

Here's my docker-compose:
version: '3'
services:
nodered:
container_name: nodered
image: nodered/node-red

- "1880:1880"
volumes:

depends_on:

cmak:
image: hlebalbau/kafka-manager
container_name: cmak
restart: always
depends_on:
- kafka
- zookeeper
ports:
- "9080:9080"
environment:
- ZK_HOSTS=zookeper:2181

command: bin/cmak -Dconfig.file=/opt/cmak/conf/application.conf -Dhttp.port=9080
volumes:

My port 9000 is already used by Portainer and it works properly, but when I'm trying to run Kafka manager on 9080, I'm getting this error without any further explanation:
nodered | 14 Sep 21:59:41 - [info] Starting flows

cmak | Oops, cannot start the server.
cmak | java.lang.RuntimeException: No application loader is configured. Please configure an application loader either using the play.application.loader configuration property, or by depending on a module that configures one. You can add the Guice support module by adding "libraryDependencies += guice" to your build.sbt.

I have a feeling it's either my path to kafka-manager is wrong or I might have to expose the hostname on my kafka container...
