net9 gRPC Json Transcoding - how to fill "Details" in reponse with error?

[k0st1x]

based on #49196 & #51394
i need an example, how to write details in json error.
currenlty i've tryied the next code on grpc service method:

var metadata = new Metadata();
var binStatus = new Status { Code = 401, Message = "error status" };
binStatus.Details.Add(Any.Pack(new StringValue { Value = "rpc argument exception" });
using var memoryStream = new MemoryStream();
binStatus.WriteTo(memoryStream);
metadata.Add("grpc-status-details-bin", memoryStream.ToArray());
throw new RpcException(new Status(), metadata);

but i've got exception on writing response "InvalidOperationException: Type registry has no description for type name 'StringValue'."
any guide or advice welcome - how to achive detailed json error message?
