AttributeError: 'str' object has no attribute 'get' [ThingsBoard IoT gateway version: 2.9]

[santobedi]

Describe the issue The error arises after installing ThingsBoard IoT gateway version: 2.9 and updating the config files. I didn't have this error with earlier version of the gateway.

Connector name (If you need help with some connector/converter): Modbus and MQTT connectors

Error traceback (If it was raised):

iots@iot2056:/etc/thingsboard-gateway/config$ sudo python3 -c 'from thingsboard_gateway.gateway.tb_gateway_service import TBGatewayService; TBGatewayService("./tb_gateway.yaml")'

[Update] I reinstalled the gateway from pip. Now, I get AttributeError: 'ModbusTcpClient' object has no attribute '_in_waiting'.

Is it a BUG?

In addition, the telemetry value of MQTT is strange!

Following is a part of the config file (timeseries):

	{
					"type": "double",
					"key": "current_phase_1",
					"value": "${current_phase_1}"
				}

The telemetry received for this config is:

(Last update time) 2021-12-28 09:01:41 (Key) current_phase_1 (Value) ${current_phase_1}

In the earlier gateway version, I used to get a proper value.

Hi @santobedi, there is no new release, so you have to use the newest Gateway version via the master branch and install it from the source.

Hi @samson0v, I installed the newest Gateway from here. Error is still there ,

AttributeError: 'ModbusTcpClient' object has no attribute '_in_waiting'

Is it a bug or did I miss something else?

[samson0v]

Hi @santobedi, I think you have the same problem as this.

Hi @santobedi, any updates? Can we close the issue?

[santobedi]

Hello @samson0v,

The issue with Modbus connector was still there. I used an alternative option in my project (used only MQTT).

Hi @santobedi, update, please, your Gateway to the newest version and send the logs if the problem isn't gone.
