I am trying to send data to azure iot hub, for that I am using the example of flow that is in the library. I set my iot hub values but I receive in the debug that it is not authorized.  
Maybe is because I am sending the incorrect deviceID.Where can I find the device ID?? Here I send you my IOT HUB from Azure

When I try to send data from the PLC I get this error:

TypeError [ERR\_INVALID\_ARG\_TYPE]: The first argument must be one of type string, Buffer, ArrayBuffer, Array, or Array-like Object. Received type undefined

Do you know what can I do to solve the problem?
