[HELP] - RPC mqtt_connector - RPC not handled

[rosiste]

Hello, I have the Thingsboard Gateway v3.5.1 last snapshot build installed in a docker environment on a Ubuntu 24.04.1 LTS server. I have some devices connected to Thingsboard Gateway throught central MQTT broker. I'd like to control these devices throught MQTT with RPC requests, but I'm always get the following error message:

2024-09-15 23:09:29 - |INFO| - [mqtt_connector.py] - mqtt_connector - server_side_rpc_handler - 971 - Incoming server-side RPC: {'device': 'shelly-test-b1355c', 'data': {'id': 102, 'method': 'Switch.Set', 'params': 'true'}, 'id': <tb_gateway_mqtt.TBGatewayMqttClient object at 0x70bba8e46f60>}

But I can control the device with simple mosquitto client with the following command:

mosquitto_pub -h 10.66.50.20 -p 1883 -t 'shelly/shelly-test-b1355c/rpc' -m '{"method":"Switch.Set","params":{"id":0,"on":false}}' -u 'user' -P 'pwd' -i 'tb-gateway'

Versions (please complete the following information):

• OS: 24.04.1
• Thingsboard IoT Gateway version 3.5.1 last snapshot (16/09/2024) docker image build master branch

Found following line in debug log even if serveSideRpc section is present in config file. Config file checked with public online JSON validator without errors.

2024-09-16 20:08:52 - |DEBUG| - [mqtt_connector.py] - mqtt_connector - load_handlers - 323 - 'serverSideRpc' section missing from configuration

Hi,

This issue relates to one of previous versions of the gateway and should not appear in the latest one. Please try to use the latest version.

Feel free to open a new issue in case of discovering any misbehaving.
