Tb_gateway 3.5.1 which was collecting data from a mall plant we have. We have 20 units with telemetry collection, the majority of which are BACnet.

After releasing release 3.5.3, three applications stopped, two we managed to reestablish but 1 presents an error, which supports what was mentioned by friend "jurkov".

follow logs.

A workaround would be to downgrade to 3.5.1. I fixed line 174 in tb_client.py and replaced 'DEBUG' with 10. (To be able to use MQTTS).

Hi @imbeacon / @samson0v / @jurkov,

i have downgraded gateway with version 3.5.1 and replaced 174 line, but still same error reoccurring.

Line 174: if self.__logger.isEnabledFor('10'):

Error : convert count=len(dict_result["attributes"]))

[jurkov]

Try tp replace the string '10' with the integer 10.
