Clarification on starting Edge using Docker

Hello,

I am having issues running the Edge docker container. With the image from https://hub.docker.com/r/openems/edge, I ran

docker run --name openems_edge -p 8080:8080 -d openems/edge

The container logs show

11:05:12.039 [_cycle] INFO io.openems.edge.controller.debuglog.ControllerDebugLogImpl - [ctrlDebugLog0] _appManager[AppValidateWorker=App.Core.Meta[App.Core.Meta: JSON [null] is not an Enum], waitingForModified=false|State:INFO: Defekte App erkannt] _componentManager[State:FAULT: Applying the default configuration failed.] _sum[State:Fault]

I assume this is likely a missing configuration file issue. Where can I find a template for a configuration file and where do I need to place it ?

Best regards
