 안녕하세요.

구글 로그인시 authService에 setRefreshToken 함수를 불러오면서 setHeader오류가 발생합니다.

  @UseGuards(GqlAuthGuard('google'))
  @Get('google')
  async socialGoogleLogin(
    @Req() req: Request & IOAuthUser,
    @Res() res: Response & IContext,
  ) {
    let user = await this.usersService.findOne({
      findOneUserInput: { email: req.user.email },
    });
    if (!user) {
      user = await this.usersService.create({
        createUserInput: {
          email: req.user.email,
          password: req.user.password,
          name: req.user.name,
        },
      });
    }
    await this.authService.setRefreshToken({
      user,
      context: res,
    });
    res.redirect('http://localhost:5500/social-login.html');
  }

  async setRefreshToken({ user, context }: IAuthServiceSetRefreshToken) {
    const refreshToken = await this.jwtService.sign(
      { sub: user.id },
      { secret: 'coex', expiresIn: '4h' },
    );
    context.res.setHeader(
      'set-Cookie',
      `refreshToken=${refreshToken}; path=/;`,
    );
  }

@Injectable()
export class JwtRefreshStrategy extends PassportStrategy(Strategy, 'refresh') {
  constructor() {
    super({
      jwtFromRequest: (req) => {
        const cookies = req.headers.cookie;
        const refreshToken = cookies.replace('refreshToken=', '');
        return refreshToken;
      },
      secretOrKey: 'coex',
    });
  }

  async validate(payload: any) {
    return { id: payload.sub };
  }
}
