417 - The device's deployment configuration is not setの対処方法

事象

IoT HubでIoT Edge Deviceを作り、（IoT Edge DeviceにModule追加せずに）エッジデバイスでIoT Edgeランタイムを起動すると、IoT Edge DeviceのEdge Runtime Responseに417 - The device's deployment configuration is not setというエラーが表示されます。

また、エッジデバイスでedgeAgentとedgeHubの2つのDockerコンテナが起動するはずなのが、edgeAgentしか起動しません。

pi@raspberrypi:~ $ docker ps
CONTAINER ID        IMAGE                                      COMMAND                  CREATED             STATUS              PORTS               NAMES

pi@raspberrypi:~ $

edgeAgentのログで、ConfigEmptyExceptionが発生していることが分かります。
