'NoneType' object has no attribute 'upper'

Describe the issue Create description about your issue, and your actions to solve it. I am having an issue integrating modbus serial with thingsboard gateway, where the device is created on thingsboard and modbus is connected but no attributes is being created providing at the log this error "'NoneType' object has no attribute 'upper'" At first I was working with thingsboard gateway as a package the one at this link https://thingsboard.io/docs/iot-gateway/install/deb-installation/ then after following different issues I installed the latest version from source but the same error is still here, please help!

Configuration (Attach your configuration file) Notate: Remove Access token from file if you wanna attach tb_gateway.yaml

Connector name (If you need help with some connector/converter): [e.g. MQTT Connector] Modbus Serial

Hi @io-r-ahmed ,

Thank you for your message it is a bug, I will fix it in new release. As a workaround you are able to add parameters "wordOrder":"LITTLE" and "byteOrder":"BIG" into timeseries object configuration.

Hello, Thanks a lot for your reply. I have done so where my final config file is: {

"server": {

"name": "Modbus Default Server",

"type": "serial",

"method": "rtu",

"port": "/dev/ttyUSB0",

"baudrate": 9600,

"timeout": 35,

"devices": [

  {

    "unitId": 1,

    "deviceName": "Serial Machine",

    "attributesPollPeriod": 5000,

    "timeseriesPollPeriod": 5000,

    "sendDataOnlyOnChange": true,

    "attributes": [

      {

        "wordorder": "LITTLE",

        "byteOrder": "BIG",

        "tag": "test",

        "type": "long",

        "functionCode": 4,

        "registerCount": 1,

        "address": 4

      }

    ]

  }

]

}

But the same error is still not solved.

Best Regards.

And Kindly check the attached log file on running thingsboard for more details.

Best Regards.

Hi @io-r-ahmed ,

type long in your config equals to 32uint, but at the same time 32uint are take 2 registers, so the gateway cannot parse received data. Please try to change type parameter in your configuration file to 16uint and probably you will be able to read the value.

Hi Gents, I am new in to Thingsboard(TB) and trying to connect TB CE into gateway and MQTT. Could you please help me crack the issue below:

@io-r-ahmed @zbeacon Note that 'NoneType' object has no attribute 'upper' is one of the 2 parsing issues I experienced after tackling JSONDecoderError from MQTT.JSON config file.

Situation: I have setup Thingsboard community edition (CE) in my local development environment and I want to connect Thingsboard CE to an external real-time messaging system (Pub/Sub or Kafka, etc.) Task: As dev, I want to subscribe telemetry messages down from a device that generates MQTT messages to TB server, and later, use IoT rules engine to send actuation/query messages from the TB server to the devices.

Action: I have Thingsboard CE server running both locally and Demo instance. I used installation guide to configure a Thingsboard gateway that allow communication through MQTT connector and I have an MQTT client that simulate a device publishing topics and telemetry. The gateway provision is based on two files respectively tb-gateway.yaml (Contain Thingsboard CE server endpoint & redirect to mqtt.json) and mqtt.json (Contain all topic structure & endpoint to the Manager/MQTT) https://thingsboard.io/docs/iot-gateway/getting-started/

Results: On Thingsboard server screen, gateway device latest telemetry shows mqttbrokerconnectoreventproduced and mqttbrokerconnectoreventsent along eventproduced are 0 and logs/tb-connection.log shows subscription success to the targeted topic published by MQTT client. On gateway console, during gateway restart there’s a simple JSON decoder error. And “‘NoneType’ object has no attribute” (Being recreated). However, I am able to post telemetry from the gateway using curl API client as in hard coded and it appears On Thingsboard server screen as attribute and value of the gateway device latest telemetry.

kindly note more logs for this ticket.

Hi @malinglb ,

Thank you for your interest in ThingsBoard IoT gateway, but your question doesn't relate to the general topic of this issue. It looks like you have an issue with your payload from external broker - the gateway cannot parse it as a json, so it cannot convert the incoming value. Please check it and make sure that incoming data from external broker is json formatted. If you have different payload, you should use custom converter to parse data.

@zbeacon thank you for the feedback. Yes, I'm getting payload from an external broker and I formatted the message as json. Will try to publish to the custom converter.
