401 unauthorized문제

안녕하세요 제로초님 LocalGuard에서 can으로 넘어가지가 않아서 질문드립니다.

import { ExecutionContext, Injectable } from '@nestjs/common';
import { AuthGuard } from '@nestjs/passport';

@Injectable()
export class LocalAuthGuard extends AuthGuard('local') {
  async canActivate(context: ExecutionContext): Promise<boolean> {
    const request = context.switchToHttp().getRequest();
    console.log('LocalAuthGuard canActivate - request.body:', request); // 추가 로그

    console.log('LocalAuthGuard canActivate - before super.canActivate'); // 추가 로그
    let can = await super.canActivate(context);
    console.log(can);

    if (can) {
      const request = context.switchToHttp().getRequest();
      console.log('login for cookie');
      console.log('request.user:', request.user); // 추가 로그
      await super.logIn(request);
    }

    return true;
  }
}

여기서 보면 requsetbody에는 request.body: { teacherId: 'hee', password: '12534' } 이렇게 제가 설정한값이 들어가고

이렇게 에러가나는데 원인은 잘모르겠습니다. 혹시 어떤부분을 살펴봐야할까요? 추가로 저기이외에 strategy쪽에는 console찍은게 아에 안들어옵니다.
