[[topics]] is required error on WeeWX-MQTTSubscribe
Vrishab Kakade
I did a fresh install of the latest MQTTSubscribe with Weewx 5 and I get the below error when I start weewx, but the simulation works just fine.

ValueError: [[topics]] is required.
Any idea why this would fail? I printed the value for topics_dict and it seems to be picking the correct values, but it also seems to be picking None.
topics_dict {'unit_system': 'METRIC', 'pico/temperature': {'subscribe': 'True', 'name': 'outTemp', 'ignore': 'False', 'message': {'type': 'individual'}}}
topics_dict None
This is my configuration.
