Grpc parsing json formated string

I have a class that is Json serialized but on the server it shows an error.

My question is, Why is Grpc not treating string as string. If the DataStatus class does not have the Status property it works.

Microsoft Visual Studio Community 2019 Version 16.11.8 Grpc.AspNetCore 2.41.0

[11:34:08.657  DBG][0HME4VFKP1S26:00000001] Grpc.AspNetCore.Server.ServerCallHandler: Reading message.

// protos
message AlertMessage {
	string id = 1;
	string command = 2;
	string message = 3;
	string type = 4;
}

//c#

string message = JsonSerializer.Serialize(new DataStatus { SerialNo = "12334", Status = updateStatus });
await _grpc.AlertAsync(new AlertMessage { Id = id.ToString(), Command = "ReceiveNewData", Message = message, Type = "update" });

//
public class UpdateStatus
{
   public string Status {get;set;} = "Done"
   public DateTime UpdateDateTime {get;set;} = DateTime.Now;
}
public class DataStatus
{
  public string SerialNo {get;set;}="";
  public UpdateStatus Status {get;set;} = new();

It shouldn’t matter that there is a JSON string.

Could you upload a reproduction of the problem? I will take a look.
