Fixed the exception:

https://github.com/traccar/traccar/commit/b9875d4076a6c88b4da6d6b296f9496f525091fe

But I don't think it would be possible to handle responses as they are not structured in any proper formats.

Really appreciate your quick support and fix, thank you very much.

I will reach out to the manufacturer for the response formats :)
