JSON decode error in rtl_433_mqtt_hass.py

[ArcticSheet]

Hello, I am trying to add my rtl_433 devices to get auto discovered but whenever I try to run the add on which runs this wrapper script: rtl_433_mqtt_hass.py

I get the following error:
ERROR:root:JSON decode error: 2025-03-13T17:42:02.309197-0700

I also get the following error:

TypeError: argument of type 'int' is not iterable

Is it having trouble trying to decode the T in the UTC time?

Why am I getting argument of type 'int' is not iterable?

I appreciate any help in this matter. Thank you!
