   Look like it crashed in https://github.com/grpc/grpc-go/blob/682ed1a71602fa94a9b9c56d2b2b2a716bccd036/internal/status/status.go#L155, which is called in https://github.com/grpc/grpc-go/blob/682ed1a71602fa94a9b9c56d2b2b2a716bccd036/status/status.go#L94
   
   ```
   func FromError(err error) (s *Status, ok bool) {
   	if err == nil {
   		return nil, true
   	}
   	if se, ok := err.(interface {
   		GRPCStatus() *Status
   	}); ok {
   		return se.GRPCStatus(), true
   	}
   	return New(codes.Unknown, err.Error()), false
   }
   ```
   It's quite strange as this function has checked if `err` is nil before calling it.
   
   Can it be reproduced by running another client writing in Go?
