Im trying to create a database in spring boot using MongoDB and two errors keep reoccurring.

The first error i get is with the in-built MongoDB function findAll which gives me the error Failed to instantiate com.accountservice.accountservice.Models.User using constructor NO_CONSTRUCTOR with arguments which i dont quite understand why i am getting.

The second problem im encountering is when i try to find specific users in my database and use findbyFirstName which doesn't really give me an error but returns nothing at all.

Here is my code;

User Class;

@Document(collection = "AllUsers")
public class User {

 private String bloodGroup;
 private String firstName;
 @Indexed(direction = IndexDirection.ASCENDING)
 private String _surname;
 private String _email;
 private String _password;
 private String _addressline;
 private String _postcode;

 // Constructor // Getters Setters

Account Service Class;

@Service
public class AccountService 

 @Autowired
 private UserRepository UserRepo;

 public User getByfirstName(String firstName)
 return UserRepo.findByFirstName(firstName);
 

 public List<User> getAll() // This does not work
 return UserRepo.findAll();
 

 

User Repository Class;

@Service
@Repository
public interface UserRepository extends MongoRepository<User, String> 

 public User findByFirstName(String firstName);

Controller Class;

@Component
public class As_Controller 

 @Autowired
 private AccountService Service_functions;

 private UserRepository UserRepo;

 public As_Controller(UserRepository userRepo) 
 UserRepo = userRepo;
 

 @ResponseBody
 @GetMapping("/getUser/firstName") // This does not return anything
 public User getUser( @PathVariable String firstName )
 System.out.println("Working"); // This prints in console
 return Service_functions.getByfirstName(firstName);
 

 @GetMapping("/getAll")
 public List<User> getAllUsers() // This does not work
 return Service_functions.getAll();
 

Any help/suggestions on this matter would be appreciated!
