hi, I pull the repository of spicedb from github and run with http-gateway enabled, all of the RESTful api which I forked from url(authzed.com/docs/REST API Reference) got response with "code:14 message:connection error: desc = \"error reading server preface: EOF\" ", otherwise, I have changed the Authorization same with grpc-preshared-key in the RESTful request, any suggestions about that?
