FIPY: Unhandled exception in thread started by <bound_method>

[tushar44]

We are using FIPY module as Lora nano-gateway and using WiFi to push data to cloud.
After 5 days of continuous operation, we are getting following error.

Unhandled exception in thread started by <bound_method>
Traceback (most recent call last):
File "MQTTMsgHandler.py", line 266, in _io_thread_func
File "MQTTMsgHandler.py", line 167, in _receive_packet
TypeError: object of type 'function' has no len()

This error causes loss of Wifi and AWS mqtt connection and data is stopped being pushed to cloud.

We are using firmware version: 1.17.3.b1
