&rt.GoString{Ptr:(unsafe.Pointer)(nil), Len:6} has nil pointer while its length is not zero! #473

When I make stress testing, 1400 more request success, only one request fails caused by a panic below, I understand the error message literally. But have no idea how to fix it. Can anyone tell me more info on what may cause the panic, thanks

This seems to be a concurrence problem, the string is written badly. You could add -race in test to detect the concurrence problem.
