Hi, when I use the latest version I get an error when calling a Lambda. 

I get this error:
Lambda process returned error status code: 1. Output:
awssvc           | 2019-05-10T22:23:19.822966331Z Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post http://%2Fvar%2Frun%2Fdocker.sock/v1.29/containers/create: dial unix /var/run/docker.sock: connect: permission denied
awssvc           | 2019-05-10T22:23:19.822969899Z must specify at least one container source

I'am using the Lambda in a docker. 

You can find my setup here: https://github.com/blaart/stream-my-changes
After forcing to use the 0.9.1 version all works fine again.  

plugin_configs = load_plugins()
    plugin_run_params = ' '.join([
        entry.get('docker', {}).get('run_flags', '') for entry in plugin_configs])
    services = os.environ.get('SERVICES', '')
    entrypoint = os.environ.get('ENTRYPOINT', '')
    cmd = os.environ.get('CMD', '')
    user_flags = os.environ.get('DOCKER_FLAGS', '')
    image_name = os.environ.get('IMAGE_NAME', constants.DOCKER_IMAGE_NAME)
    service_ports = config.SERVICE_PORTS
    force_noninteractive = os.environ.get('FORCE_NONINTERACTIVE', '')
    
    ports_list = sorted(service_ports.values())
    start_port = 0
    last_port = 0
    port_ranges = []
    for i in range(0, len(ports_list)):
        if not start_port:
            start_port = ports_list[i]
        if not last_port:
            last_port = ports_list[i]
        if ports_list[i] > last_port + 1:
            port_ranges.append([start_port, last_port])
            start_port = ports_list[i]
        elif i >= len(ports_list) - 1:
