The same happened to me: I just tried to install psa-car-controller (which I got running), but when trying to set up the user config, I got exactly the same error message. In my case it is for a Peugeot car. I can still log in via the MyPeugeot app.

I have the same problem. That seems to be a recurring issue. It happend before and this workaround still works #938 (comment)
I just tested it with the 1.51.1 version.
Hope that helps.

Thanks, this workaround worked for me too. I just placed the latest . apk in the correct folder and then rebooted the docker container. After that it worked again.
