> +Question:+
> IoTAgent-LoRaWAN: Error decoding CaynneLPP message
> +Description:+
> I've published this question in StackOverflow I've followed the official docs and apparently all docker containers are running with no errors, however, the fiware-IoT-agent (IoTAgent-LoRaWAN) is having issues to decode CayennLpp messages as you can see:
> fiware-iot-agent | {"timestamp":"2020-06-23T11:45:53.689Z","level":"info","message":"New message in topic"}
> fiware-iot-agent | {"timestamp":"2020-06-23T11:45:53.690Z","level":"info","message":"IOTA provisioned devices:"}

> fiware-iot-agent | {"timestamp":"2020-06-23T11:45:53.691Z","level":"error","message":"Error decoding CaynneLPP message:Error: Invalid CayennLpp buffer size"}
> fiware-iot-agent | {"timestamp":"2020-06-23T11:45:53.691Z","level":"error","message":"Could not cast message to NGSI"}
> This is how I'm provisioning the device

>       "device_id": "{{node}}",
>       "entity_name": "LORA-N-0",
>       "entity_type": "LoraDevice",
>       "timezone": "Europe/Madrid",
>       "attributes": [
>         {

>           "name": "Pot_Value",
>           "type": "Number"
>         }

>         }
>       }
>     }
>   ]
> }
> Of course, as I've said in StackOverflow, those {{}} are environment variables in Postman to avoid get sensible information published, anyway ... I'm not sure about the field "password": "{{TTN_app_pw}}" that I've used. Also ... I think this site should have better formatting options to publish this questions (or maybe I don't know the formatting tags)
> Thank you all.
