this is the code :

using Microsoft.AspNetCore.Mvc;

namespace WebApplication1
{
    public class Program
    {
        public static void Main(string[] args)
        {
            var builder = WebApplication.CreateBuilder(args);

            // Add services to the container.

            builder.Services.AddControllers();
            // Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle
            builder.Services.AddEndpointsApiExplorer();
            builder.Services.AddSwaggerGen();

            var app = builder.Build();

            // Configure the HTTP request pipeline.
            if (app.Environment.IsDevelopment())
            {
                app.UseSwagger();
                app.UseSwaggerUI();
            }
            app.MapPost("/", ([FromBody]Parameters para) =>
            {
                return "ok";
            });
            app.UseHttpsRedirection();

            app.UseAuthorization();


            app.MapControllers();

            app.Run();
        }
    }

    public class Parameters
    {
        public DateTime? Date { get; set; }
    }
}

when i request , the parameter is :
{
"date": ""
}

the important is commany project common webapi allow and not reject advice, the sample parameters is many。
in Controller mod, builder.Services.AddControllers.AddNewtonsoftJson or AddJsonOptions can solve,
the next important is ,if the miniwebapi cut off too many Important function，use mini api meaningless。

this is the result:

It's not clear to me what you're actually asking for here.

"" is not a valid DateTime string, so is rejected as invalid.
