-  Because the query handlers are not yet registered with gRPC, you see a not implemented or localhost cannot connect error. This error is expected behavior, because you still need to register the query handlers.

-Make the required changes to the `x/hello/module.go` file.

-1. Add `"context"` to the list of packages in the import statement.
