Custom status codes return cors error

[SpiritLing]

1. Returned in custom permission validation

// custom status code
context.Result = new StatusCodeResult(701);

2. Set up in the middleware

if (httpContext.Response.StatusCode == 701 && httpContext.Request.Method != "OPTIONS")
{
    var body = new ResultDTO<string>()
    {
        Code = 701,
        MsgKey = "Jwt Token Expired",
        Message = "Jwt token expired, permission verification failed."
    };
    var bodys = JsonConvert.SerializeObject(body);

    var bytes = Encoding.UTF8.GetBytes(bodys);

    await httpContext.Response.Body.WriteAsync(bytes, 0, bytes.Length);
}

3. error

// console
fail: Microsoft.AspNetCore.Server.Kestrel[13]
      Connection id "0HM69HI8TSMUD", Request id "0HM69HI8TSMUD:00000002": An unhandled exception was thrown by the application.
System.InvalidOperationException: Response Content-Length mismatch: too few bytes written (0 of 54).

//http request
cors error

I think you will need to create an issue for this or post somewhere like Stack Overflow.
