It doesn't return error because it wouldn't be any when with a Blocking semantic, returned error does nothing but causing confusion, more often, people thought it is returned by the task. Since it is async task, the callframes would not be available for production mode, you can export Environment Varaible ASYNC_CF=true to enable callframes capturing when debugging. IMPORTANT: do NOT call SubmitBlocking inside the async task, it is likely to cause a deadlock, call SubmitNonBlocking instead when number of tasks is relatively small.
