Модули Картера не зарегистрированы в приложении ASP.NET Core. ⇐ C#

[Anonymous]

Я определил модули Carter в своем приложении, но ни один из них не запускает точки останова во время запуска, и никакие маршруты не регистрируются. В чем проблема?
using Carter;
using MediatR;
using Microsoft.AspNetCore.Mvc;
using Microsoft.EntityFrameworkCore;
using OneOf;
using MyApp.API.Data;
using MyApp.API.Data.Models;
using MyApp.API.Models;

namespace MyApp.API.Features.Sheets;

public static class GetSheet
{
public record Command(string SheetId) : IRequest;

public class Handler : IRequestHandler
{
private readonly ApplicationDbContext context;

public Handler(ApplicationDbContext context)
{
this.context = context;
}

public async Task Handle(Command request, CancellationToken cancellationToken)
{
var sheetCells = await context.SheetCells
.Where(x => x.SheetId == request.SheetId)
.ToListAsync(cancellationToken: cancellationToken);

if (sheetCells == null)
{
return new NotFound();
}

var sheet = new Sheet(sheetCells);

return sheet;
}
}

public class Endpoint : ICarterModule
{
public void AddRoutes(IEndpointRouteBuilder app)
{
app.MapGet("/api/v1/{sheetId:string}",
async ([FromBody]Command command, IMediator mediator) =>
{
var result = await mediator.Send(command);
return result.Match(
cell => Results.Ok(cell),
_ => Results.NotFound());
});
}
}
}

Program.cs
using Microsoft.EntityFrameworkCore;
using MyApp.API.Data;
using Carter;

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddDbContext(x =>
x.UseSqlServer(builder.Configuration.GetConnectionString("Default")));
builder.Services.AddMediatR(c => c.RegisterServicesFromAssemblyContaining(typeof(Program)));

builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();
builder.Services.AddCarter();

var app = builder.Build();

app.UseSwagger();
app.UseSwaggerUI();

app.MapCarter();

app.Run();
