System.InvalidOperationException problem cannot use CRUD methods

Question

community!

I am trying to make a booking system with C# full stack.

I made all CRUD operations for APIs, but I am constantly receiving this problem: System.InvalidOperationException: Unable to resolve service for type 'WebAPI.Data.BookingService' while attempting to activate 'WebAPI.Controllers.BookingController' when trying to use PUT method.

PUT method:

[HttpPost]
public async Task<ActionResult<Booking>> AddBooking([FromBody] Booking booking)
{
    try
    {
        Booking added = await _bookingService.AddBookingAsync(booking);
        return Created($"/{booking.Id}", booking);
    }
    catch (Exception e)
    {
        Console.WriteLine(e.Message);
        return StatusCode(500, e.Message);
    }
}

I also added the services into Program.cs

builder.Services.AddScoped<BookingDBContext>();
builder.Services.AddScoped<IResourceService, ResourceService>();
builder.Services.AddScoped<IBookingService, BookingService>();

How can I solve it? Does anyone know other reasons why it throws me an exception? As I read on previous posts, the problem could be on Program.cs because I didn't add the services, but, in my case, they are.
