Unexpected exception - Websocket API error with Gree HVAC

Hello,
I’ve been struggling with Gree AC integration for months. The official integration works fine, but it shows target temperature as AC’s temperature read, which doesn’t allow me to use some automations. Thankfully HomeAssistant-GreeClimateComponent allows to add external temp sensor to climate entity.

I can’t get it to work, because every time I interact with Gree through HA I get timeouts. Furthermore, the Websocket error is displayed. I was suggested that it has to do with my version rollbacks, but as I checked it is also thw problem in a clean installation. I’m sending logs in the attachments. Could you please help me resolving the problem?
Best regards,
Jakub
