telegram extension cannot construct IncomingMessageEntity for commands

[vitaB]

I tried a simple bot that only logs the incoming messages.

@ApplicationScoped
class TelegramRoute {
    @Produces
    fun myRoutes() = routes {
        from("telegram:bots")
                .log("\${body}")
                .to("telegram:bots")
    }
}

This works for a normal text message, as a jar as well as native image. But as soon as I send a command (e.g. /start or /echo) the native variant throws the following errors:
