[HELP]When I try to use CustomiMqttUplinkConverter,The code 'self. _ configuration. get (' extension-configuration ')' is always None

Describe the issue
When I try to use CustomiMqttUplinkConverter,The code 'self. _ configuration. get (' extension-configuration ')' is always None

Configuration (Attach your configuration file)
Notate: Remove Access token from file if you want to attach a tb_gateway.yaml
mqtt.json

Connector name (If you need help with some connector/converter):
MQTT Custom Converter.Perhaps similar custom converters also have similar issues

Error traceback (If it was raised):

So it always runs until this code=> dict_result["telemetry"] = {"data": int(body, 0)}  # if no specific configuration in config file - just send data which received,And then this code seems to have an issue, it will report an error↓

|ERROR| - [tb_gateway_service.py] - tb_gateway_service - __send_to_storage - 1070 - 'str' object has no attribute 'get'

I am trying to change it to "extensionConfiguration", which is consistent with expectations. Is it due to the Camel Case conversion?
Additionally, in the else code block, I changed it to append to resolve the error of 'str' object has no attribute 'get'

I hope you can see and give me a reply, thank you!

Versions (please complete the following information):

• OS: Centos 7
