Hi,  
I'm using opcua-contrib and opcua-IIOT-contrib. My goal is to use a http in to:

1. Returning the variables available
2. Returning the value of a nameId in url parameter

Till now I can set the target and if I use the nodes hardly setted, my http out doesn't contain an object!

Thanks for the help
