          Question:
          Publish MQTT message in fiware via MQTT Paho library

          Description:
          I am working on this Fiware flow:

          I have used efrecon/mqtt-client as MQTT client based on mosquitto_pub so that the data can be consumed from Grafana.
          docker run -it --rm --name mqtt-publisher efrecon/mqtt-client pub -h 172.31.85.246 -p 31624 -m "AGV_Th|25" -t "/ul/5jggokgpepnvsb2uv4s40d59ov/agv001/attrs"

          In the following example, a key-value pair is sent to populate a persistence with Crate DB and then consumed with Grafana.

          I am testing with a new python mqtt-paho based client without achieving the same result as with the mosquitto_pub based docker client. For instance:
          import paho.mqtt.client as mqtt
          client = mqtt.Client()
          client.connect("172.31.85.246", 31624)
          client.publish("/ul/5jggokgpepnvsb2uv4s40d59ov/agv001/attrs","

          {\"agv_th\":65}

          ")

          Any ideas?
