this one is better. more logs like this would be helpful.

can not re-produce this error by run npm run demo two times.

please submit more log next time u meet this problem.

and if u could provide a way to re-produce this behavior, that will be super helpful.

please feel free to re-open this issue if you can provide Steps to reproduce the behavior. thanks.
