This is my code
And my api is working just fine
But the CORS is not working

using DatingApp.Data;
using Microsoft.EntityFrameworkCore;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddControllers();
builder.Services.AddCors(options =>
{
    options.AddPolicy(name: "AllowSpecificOrigins",
                      policy =>
                      {
                          policy.WithOrigins("http://localhost:4200").AllowAnyHeader().AllowAnyMethod().AllowCredentials();
                      });
});
builder.Services.AddDbContext<DataContext>(opt =>
{
    opt.UseSqlite(builder.Configuration.GetConnectionString("DefaultConnectionString"));
});

var app = builder.Build();

// Configure the HTTP request pipeline.

app.UseRouting();

app.UseCors("AllowSpecificOrigins"); // Use the named CORS policy

app.UseAuthorization();

app.MapControllers();

app.Run();

I have looked everywhere ,, i am not able to figure out what is wrong with this code

It was expected that , with CORS configured , My angular frontend would be able to access the backend
But there is an error somewhere
