Error while validating the service descriptor 'ServiceType: Microsoft.AspNetCore.Identity.IUserClaimsPrincipalFactory`1

Question

This error occurs while trying to add-migration for the first time. I have added the extension method and my service class

public void ConfigureServices(IServiceCollection services) {

        services.AddCors();
        services.AddControllers();
        
        services.Configure<AppSettings>(AppSettings);
        services.ConfigureJWT(Configuration);
        services.ConfigureIdentity();
        services.AddScoped<ILoginService, LoginService>();
        services.AddScoped<IUserClaimsPrincipalFactory<ApplicationUser>, CustomClaimPrincipalFactory>();
    }

public static void ConfigureIdentity(this IServiceCollection services) {

        var builder = services.AddIdentityCore<ApplicationUser>(o =>
        {
            o.Password.RequireDigit = true;
            o.Password.RequireLowercase = false;
            o.Password.RequireUppercase = false;
            o.Password.RequireNonAlphanumeric = false;
            o.Password.RequiredLength = 6;
            o.User.RequireUniqueEmail = true;
        });
        builder = new IdentityBuilder(builder.UserType, typeof(IdentityRole),
       builder.Services);
        builder.AddEntityFrameworkStores<AuthDBContext>()
        .AddDefaultTokenProviders();


    }

public class CustomClaimPrincipalFactory : UserClaimsPrincipalFactory<ApplicationUser, IdentityRole> {

    public CustomClaimPrincipalFactory(
        UserManager<ApplicationUser> userManager,
        RoleManager<IdentityRole> roleManager,
        IOptions<IdentityOptions> optionsAccessor)
        : base(userManager, roleManager, optionsAccessor)
    {
    }

    protected override async Task<ClaimsIdentity> GenerateClaimsAsync(ApplicationUser user)
    {
        ClaimsIdentity identity = await base.GenerateClaimsAsync(user);
        identity.AddClaim(new Claim("ServiceSite", user.ServiceSite ?? ""));
        return identity;
    }
}

Here is the Error again

Register the dbcontext before you configure the Identity store

services.AddDbContext<AuthDBContext>();
services.AddIdentity<IdentityUser,IdentityRole>()
                .AddEntityFrameworkStores<AuthDBContext>()
                .AddDefaultTokenProviders();
