Root Cause

Server-side code panics due to a nil pointer or other runtime error, causing an Internal error.

generic

中文

服务器端代码因空指针或其他运行时错误而恐慌，导致 Internal 错误。

Workarounds

  1. 95% success 
    func recoveryInterceptor(ctx context.Context, req interface{}, info *grpc.UnaryServerInfo, handler grpc.UnaryHandler) (resp interface{}, err error) {
    defer func() { if r := recover(); r != nil { log.Printf("panic: %v", r); err = status.Errorf(codes.Internal, "internal error") } }()
    return handler(ctx, req)
}
  2. 80% success 
    if req.User == nil { return nil, status.Error(codes.InvalidArgument, "user required") }

Dead Ends

Common approaches that don't work:

  1. 90% fail

    The bug will recur when the same condition is hit.

  2. 60% fail

    Without logs, you can't identify the root cause.
