Any ideas?

possibly 2 things,

1. Docker engine API version service is trying to connect to is not supported (or not specified) for your docker version

try passing DOCKER_API_VERSION: "1.41" to docker-events-notifier.environment

ref: https://docs.docker.com/engine/api/#api-version-matrix

2. Code has no nice message on this scenario, top of that it crashes when it recognises a json line and trying to compute docker event json object off it.
