[V2] Json Error on Set Modules deployment

[Strandfelt]

• V2 issue

• OS version and architecture used: Windows 10 x86_64

• Version used: 1.0.0rc22

• V2 Docker version and container type: linux

Description of the issue:

I have followed the guide on setting up the OPC Publisher module from the README of the module source here: https://github.com/Azure/iot-edge-opc-publisher
Once I finish setting the module on the IoT Edge tab of the portal, I get the error message shown in the section below, after running docker logs -f edgeAgent
The deployment generated by the Azure portal is as follows:
