我得到了一个错误的请求400，但我从后端完美地获得了我的数据。也只有当我使用React严格模式时才会发生。不知道发生了什么。添加了代码，我相信有人需要找到的问题
后端：
控制器：console.logging newLeaderboard给了我所期望的。

export const updateQuestionLeaderboard = async (req, res) => {
  const { leaderboardId } = req.params;
  const { questionIndex, playerId, playerPoints } = req.body;
  let leaderboard;

  try {
    leaderboard = await Leaderboard.findById(leaderboardId);
    leaderboard.questionLeaderboard[questionIndex].questionResultList.push({
      playerId,
      playerPoints,
    });

    const newLeaderboard = await leaderboard.save();
    console.log({ newLeaderboard });
    // console.log(newLeaderboard.questionLeaderboard[0].questionResultList);
    res.status(201).json(newLeaderboard);
  } catch (error) {
    res.status(400).json({ message: error.message });
  }
};

字符串
这是我的路线代码。路线：

router.patch(
  "/:leaderboardId/questionleaderboard",
  verifyToken,
  updateQuestionLeaderboard
);

前端：操作：

export const updateQuestionLeaderboard =
  (questionResult, id, token) => async (dispatch) => {
    try {
      const response = await fetch(
        `http://localhost:3000/leaderboard/${id}/questionleaderboard`,
        {
          method: "PATCH",
          headers: {
            Authorization: `Bearer ${token}`,
            "Content-Type": "application/json",
          },
          body: JSON.stringify(questionResult),
        }
      );
      console.log({ questionResult });
      const data = await response.json();
      console.log({ data });
      dispatch({ type: "UPDATE_QUESTION_LEADERBOARD", payload: data });
      return data;
    } catch (error) {
      console.log(error);
    }
  };

我的主机页面在前端：

const updateLeaderboard = (data, id, score) => {
    console.log("GIVE LEADERBOARD ID", id);
    dispatch(updateQuestionLeaderboard(data, id, token))
      .then((question) => {
        console.log({ question });
        setQuestionResult(question.questionLeaderboard[data.questionIndex]);
        let leaderboardData = {
          questionIndex: data.questionIndex,
          playerId: data.playerId,
          playerCurrentScore: score,
        };
        return dispatch(updateCurrentLeaderboard(leaderboardData, id, token));
      })
      .then((leaderboard) => {
        console.log({ leaderboard });
        console.log("DATA QUESTION INDEX", data.questionIndex);
        setCurrentLeaderboard(
          leaderboard.currentLeaderboard[data.questionIndex]
        );
      })
      .catch((error) => {
        // Handle any errors that might occur during the async operations
        console.error(error);
      });
  };
