Switch-multi does not turn off itself
I notice another problem, when I trigger a switch-multi, the switch does not turn itself off. It reply the error as below.
(node:31017) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): ReferenceError: state is not defined
(node:31017) DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.
