"unknown error" when changing Tesla settings

[lencioni]

I have my Tesla set up and I can see the correct states in my dashboard. If I try to change any setting, after waiting about 30 seconds (which I assume is some sort of timeout) I always end up running into "unknown error". Here is an example of trying to lock the doors:

I found this information in the logs:

Hello! I have exactly the same issue.

Previously I had a Model 3 (2020). All worked fine with HA, until I sold it in 2023 Dec.
Recently I got Model 3 Highland (2024). I wanted to use it with HomeAssistant. All information fetched from the API properly, but if I would like to change any settings (example charging level, amps etc ...), then I got the exceptions that lencioni mentioned.

I don't know if it is linked to the new car, I have no other tesla to be able to test it.

Thanks for anybody who has any idea to debug or solve the issue.
