API Invalid option killing session

Hello everyone, I'm using the typebot api with my WhatsApp customer service platform, using it I create a service flow, sometimes when the flow doesn't have the "else" defined, when the user selects an invalid option it ends up informing that the option is invalid, but at the same time it ends up killing the session, so when the user sends a message again it ends up freezing the chat since the post to continue Chat ends up failing since the session no longer exists, how to solve it?
