Description of problem

dokku-event-listener.service throws panic: runtime error: invalid memory address or nil pointer dereference errors in logs

Logs are like that:

I suppose that it crashes on last container. It's set up with --net=host option, instead of docker bridge.

is this actually fixed or not? I'm getting the same error and I'm not sure how to get rid of it...
