Description

Currently, BMI#mutate doesn't wait the result from AP so the errors are stored in AP. The only way which can return the errors to user is, calling the flush to catch the exception. That is non-intuitive.

I feel BMI#mutate should wait the result. That is to say, user can parse the exception thrown by BM#mutate to get the failed mutations. Also, we can remove the global error from AP.
