Hello everyone ,

I'm in the process of configuring a .NET 7 AOT minimal API that's integrated with a lambda function URL. However, an exception is thrown each time the API endpoint is accessed. Any assistance would be appreciated.

using Microsoft.EntityFrameworkCore;
using ReservationWebhook;
using ReservationWebhook.Models;
using System.ComponentModel.DataAnnotations;
using System.Text.Json;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddControllers();
// Add AWS Lambda support. When application is run in Lambda Kestrel is swapped out as the web server with Amazon.Lambda.AspNetCoreServer. This
// package will act as the webserver translating request and responses between the Lambda event source and ASP.NET Core.
builder.Services.AddAWSLambdaHosting(LambdaEventSource.HttpApi);

var app = builder.Build();


app.UseHttpsRedirection();
app.UseAuthorization();
app.MapControllers();

app.MapGet("/", () => "Hello World!");

app.Run();
