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.  

self.method = requests.get
        self.read_content()
        self.forward('GET')
    def do_PUT(self):
        self.method = requests.put
        self.read_content()
        self.forward('PUT')
    def do_POST(self):
        self.method = requests.post
        self.read_content()
        self.forward('POST')
    def do_DELETE(self):
        self.data_bytes = None
        self.method = requests.delete
        self.forward('DELETE')
    def do_HEAD(self):
        self.data_bytes = None
        self.method = requests.head
        self.forward('HEAD')
    def do_PATCH(self):
