Lombok @Data error

I'm getting this error

java: cannot find symbol
  symbol:   method getFirstName()
  location: variable customerDto of type dto.CustomerDto

java: cannot find symbol
  symbol:   method getFirstName()
  location: variable customerDto of type dto.CustomerDto

in this part of code:

private Customer mapToCustomer(CustomerDto customerDto) throws Exception {
        if(customerDto.getFirstName().isEmpty() || customerDto.getLastName().isEmpty() || customerDto.getEmail().isEmpty() || customerDto.getPassword().isEmpty() || customerDto.getRole().isEmpty()) {
            throw new Exception("All fields must be filled");
        }

        return Customer.builder()
                .firstName(customerDto.getFirstName())
                .lastName(customerDto.getLastName())
                .email(customerDto.getEmail())
                .password(customerDto.getPassword())
                .role(customerDto.getRole())
                .build();
    }

private Customer mapToCustomer(CustomerDto customerDto) throws Exception {
        if(customerDto.getFirstName().isEmpty() || customerDto.getLastName().isEmpty() || customerDto.getEmail().isEmpty() || customerDto.getPassword().isEmpty() || customerDto.getRole().isEmpty()) {
            throw new Exception("All fields must be filled");
        }

        return Customer.builder()
                .firstName(customerDto.getFirstName())
                .lastName(customerDto.getLastName())
                .email(customerDto.getEmail())
                .password(customerDto.getPassword())
                .role(customerDto.getRole())
                .build();
    }

even though I've used the @Data annotation in my CustomerDto class:

@Data
@Builder
@NoArgsConstructor
@AllArgsConstructor
public class CustomerDto {
    private Long id;
    private String firstName;
    private String lastName;
    private String role;
    private String email;
    private String password;
    private LocalDateTime createdAt;
    private LocalDateTime updatedAt;
}

@Data
@Builder
@NoArgsConstructor
@AllArgsConstructor
public class CustomerDto {
    private Long id;
    private String firstName;
    private String lastName;
    private String role;
    private String email;
    private String password;
    private LocalDateTime createdAt;
    private LocalDateTime updatedAt;
}

java: cannot find symbol symbol: method builder()

before you ask, I've already enabled annotation processing in my spring boot project. I don't really know what else I can do

I was trying to make a log in system for my web app, but my code doesn't seem to work

using AplikacjaWeb.Models;
using Microsoft.AspNetCore.Identity;
using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.Mvc.RazorPages;

namespace AplikacjaWeb.Pages.Registration
{
    public class RegistrationModel : PageModel
    {
        private readonly UserManager<UserModel> _userManager;
        private readonly SignInManager<UserModel> _signInManager;
        public RegistrationModel(UserManager<UserModel> userManager, SignInManager<UserModel> signInManager)
        {
            _userManager = userManager;
            _signInManager = signInManager;
        }
        [BindProperty]
        public Rejestracja /*Registration in english*/ Input { get; set; }
        public void OnGet()
        {
        }

        public async Task<IActionResult> OnPostAsync()
        {
            if (ModelState.IsValid)
            {
                var user = new UserModel { UserName = Input.Username, Email = Input.Email, PasswordHash = Input.Password };
                var result = await _userManager.CreateAsync(user, Input.Password);
                if (result.Succeeded)
                {
                    await _signInManager.SignInAsync(user, isPersistent: false);
                    return RedirectToPage("/Index");
                }
                else
                {
                    Console.WriteLine("Error");
                }
                foreach (var error in result.Errors)
                {
                    ModelState.AddModelError(string.Empty, error.Description);
                }
            }

            return RedirectToPage("/Index");
        }
    }
}

object ref not set blah blah blah

atp i have no Idea what I did wrong. In the following function:

        public async Task<IActionResult> OnPostAsync()
        {
            if (!ModelState.IsValid)
            {
                return Page();
            }

            var result = await _signInManager.PasswordSignInAsync(Input1.Username, Input1.Password, false, false);

            if (result.Succeeded)
            {
                return RedirectToPage("/Index");
            }
            else
            {
                ModelState.AddModelError(string.Empty, "Invalid login attempt.");
                return Page();
            }
        }

the PasswordManagerAsync() method is throwing the aforementioned exception

I'm getting an error "object reference not set to an instance of an object"

the code:

@model IEnumerable<WebApp.Models.Produkt>

<h1>a List</h1>

@if (Model == null || !Model.Any())
{
    <p>No products available.</p>
}
else
{
    @foreach (var product in Model)
    {
        if (product != null)
        {
            <li>
                <b>@product.name</b> - @product.category
                <a href="@Url.Action("Details", "Warehouse", new { id = product.id })">Details</a>
                <button>Delete</button>
            </li>
        }
    }
}

It appears that Model is null but I don't know how to fix it

why is there "string[] args" inside the main function parentheses?

Hello, I've just started learning c# (after doing some c++) and I wonder why it's like that since we don't even use it inside the main function, like it's just there and I'd like to know why
