Step 3 of the, "Setting Up the Demo," instructions in ThingWorx Azure IoT Hub Connector Installation and Operations Guide say, "From a Command Prompt or shell window, run npm install.
Clarification - You want to be in the ..\Thingworx-Azure-IoT-Hub-Connector-22.214.171.124\demo\edge directory when you run npm install. That's where the package.json file you'll need is located.
Good catch! Thanks again.
