 async validateUser(userEmail: string, userPassword: string) {
    const user = await this.userService.findByEmail(userEmail);
    if (user && user.password === userPassword) {
      const { id, name, email } = user;
      return { id: id, name, email };
    }else {
      throw new UnauthorizedException({
        error: 'Incorrect username or password'
      });
    }
  }

  async login(user: any) {
    const payload = { email: user.email, sub: user.id };
    return {
      access_token: this.jwtService.sign(payload),
    };
  }
