Exception in message_received when handling msg on 'openWB/chargepoint/1/get/connected_vehicle/config' - Cannot assign to field payload

Hi guys,

I did some debugging on another module I used and while doing that I recognized that my log got flooded with following messages on :

2024-05-14 16:51:31.624 ERROR (MainThread) [homeassistant.util.logging] Exception in message_received when handling msg on 'openWB/chargepoint/1/get/connected_vehicle/config': '{"average_consumption": 20000, "charge_template": 2, "chargemode": "pv_charging", "current_plan": null, "ev_template": 1, "priority": false, "time_charging_in_use": false}'

I already removed the integration and removed it from HASS, restarted HASS and install and configure it again but issue persist.

Versions:

• openwb2mqtt 0.2.1
• HASS core 2025.5.3
• openwb 2.1.3-Patch 1

Seems to occur because of another custom component. After updating this component the error here disappears.
