[HELP] - RPC mqtt_connector - RPC not handled

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'
