레파지토리 버전 다운 후 포스트맨 POST 호출시 에러 도와주세요 ㅠㅠ..

안녕하세요!

아래 에러 원인 파악이 힘들어서 도움을 요청드립니다 ㅠㅠ

import { EntityRepository, Repository } from 'typeorm';
import { Board } from './board.entity';
import { BoardStatus } from './board-status.enum';
import { CreateBoardDto } from './dto/creaate-board.dto';

@EntityRepository(Board)
export class BoardRepository extends Repository<Board> {
  async createBoard(createBoardDto: CreateBoardDto): Promise<Board> {
    const { title, description } = createBoardDto;

    const board = this.create({
      title,
      description,
      status: BoardStatus.PUBLIC,
    });

    await this.save(board);
    return board;
  }
}

왜 자꾸 create를 읽지 못한다고 하는건가요??

여기서 어디를 수정해야되는지 알려주세요 ㅠㅠ 감사합니다 ㅠㅠ
