Can't set deviceTypeJsonExpression from mqtt-config.json

using tb-gateway 1.4.0 with mqtt-config.json against demo.thingsboard.io. When I connect first time with new device, it DOES create a new device in Thingsboard but DOES NOT change the deviceType attribute from “default”.

mqtt-config.json:

...
          "topicFilter": "sensor/+/mtdotbox",
          "converter": {
            "type": "json",
            "filterExpression": "",
            "deviceNameTopicExpression": "(?<=sensor\/)(.*?)(?=\/mtdotbox)",
            "deviceTypeJsonExpression": "${$.model}",  // <--- this should work?!?
            "timeout": 60000,
            "attributes": [
...
              {
                "type": "string",
                "key": "model",
                "value": "${$.model}"
...

Here is the data I am sending to the tb-gateway from my local gateway

{ 
    "serialNumber": "00-08-00-4A-38-A3",
     "model": "MT-DOTBOX-G-915",
     "light": 972.75, 
     "temperature": 25.1875, 
      "humidity": 101.6765,
      "x_acc": 0,
      "y_acc": 0, 
      "z_acc": 1
 }

Here is the tb-gateway log showing connect. attributes, telemetry. Seems ok.

Hi,

I had the same problem - deviceTypeJsonExpression had no effect in http-config.json and always returned “default” as the device type. Using 1.4.0 now. How to get this resolved? Will the latest version of Gateway help?

Fixed: the environment variable LOADER_PATH must specify the config directory and be available from within the docker container.

in the docker host environment

GATEWAY_LOADER_PATH=/usr/share/tb-gateway/conf

in the docker-compose.yml
