Невозможно выполнить запрос в GraphQL

Question

Я пытаюсь войти в GraphQL, и я последовал руководству по простому приложению GraphQL + Spring + MySQL и переделал его для своей собственной базы данных. Но когда я пытаюсь выполнить свой запрос findAllDocuments , я получаю следующий ответ в Postman:

    "data": null,
    "errors": [
        {
            "message": "Validation error of type FieldUndefined: Field 'findAllDocuments' in type 'query' is undefined @ 'findAllDocuments'",
            "locations": [
                {
                    "line": 2,
                    "column": 5,
                    "sourceName": null
                }
            ],
            "description": "Field 'findAllDocuments' in type 'query' is undefined",
            "validationErrorType": "FieldUndefined",
            "queryPath": [
                "findAllDocuments"
            ],
            "errorType": "ValidationError",
            "path": null,
            "extensions": null
        }
    ]
}

Это сущность, которую я пытаюсь получить (у нее есть несколько сложных типов данных, таких как Group или носители, которые имеют реализацию, аналогичную классу Document , я не включил их для экономии места):

type Query {
    findAllDocuments: [Document]!
}

Это Запрос Класс распознавателя:

public class Query implements GraphQLQueryResolver {
    private final DocumentRepository documentRepository;
    private final DocumentForumRepository documentForumRepository;
    private final GroupRepository groupRepository;
    private final MediaRepository mediaRepository;
    private final UserDetailsRepository userDetailsRepository;

    @Autowired
    public Query(DocumentRepository documentRepository,
                 DocumentForumRepository documentForumRepository,
                 GroupRepository groupRepository,
                 MediaRepository mediaRepository,
                 UserDetailsRepository userDetailsRepository){

        this.documentRepository = documentRepository;
        this.documentForumRepository = documentForumRepository;
        this.groupRepository = groupRepository;
        this.mediaRepository = mediaRepository;
        this.userDetailsRepository = userDetailsRepository;
    }

    public Iterable<Document> findAllDocuments(){
        return documentRepository.findAll();
    }

    public Iterable<DocumentForum> findAllDocumentForums(){
        return documentForumRepository.findAll();
    }
    public Iterable<Group> findAllGroups(){
        return groupRepository.findAll();
    }
    public Iterable<Media> findAllMedia(){
        return mediaRepository.findAll();
    }
}

И это DocumentResolver Класс:

public class DocumentResolver implements GraphQLResolver<Document> {
    private DocumentForumRepository documentForumRepository;
    private GroupRepository groupRepository;
    private MediaRepository mediaRepository;
    private UserDetailsRepository userDetailsRepository;

    @Autowired
    public DocumentResolver(DocumentForumRepository documentForumRepository,
            GroupRepository groupRepository,
            MediaRepository mediaRepository,
            UserDetailsRepository userDetailsRepository){

        this.documentForumRepository = documentForumRepository;
        this.groupRepository = groupRepository;
        this.mediaRepository = mediaRepository;
        this.userDetailsRepository = userDetailsRepository;
    }

    public List<DocumentForum> getForums(Document document){
        return documentForumRepository.findAllById(document.getId());
    }

    public UserDetails getAuthor(Document document) throws ObjectNotFoundException {
        Optional<UserDetails> optionalUserDetails = userDetailsRepository.findById(document.getId());
        if(optionalUserDetails.isPresent()){
            return optionalUserDetails.get();
        }else{
            throw new ObjectNotFoundException();
        }
    }

    public Group getGroup(Document document) throws ObjectNotFoundException {
        Optional<Group> optionalGroup = groupRepository.findById(document.getId());
        if(optionalGroup.isPresent()){
            return optionalGroup.get();
        }else{
            throw new ObjectNotFoundException();
        }
    }

    public List<Media> getMedia(Document document) {
        return mediaRepository.findAllById(document.getId());
    }
}

Запрос, который я пытаюсь отправить от Почтальона:

{
    findAllDocuments{
        id
        title
        data
    }
}

Все работает в моем меньшем проекте, и я не могу точно определить, в чем здесь проблема. Если что-то еще нужно, пожалуйста, дайте мне знать, и я предоставлю это. Спасибо.
