我用Postman测试了所有的CRUD操作，甚至POST，但只有POST在前端应用程序中不起作用，我已经调试了几个小时，但我得到了错误。
Uncaught（in promise）AxiosError {message：'请求失败，状态代码为500'，名称：“AxiosError”，代码：'ERR_BAD_RESPONSE'，配置：{...}，请求：XMLHttpRequest，...}代码：“ERR_BAD_RESPONSE”配置：{过渡：{...}，适配器：Array（2），transformRequest：Array（1），transformResponse：数组（% 1），超时：0，...}消息：“请求失败，状态代码为500”名称：“AxiosError”请求：XMLHttpRequest {onreadystatechange：null，readyState：4、超时：0，withCredentials：false，upload：XMLHttpRequestUpload，...}响应：{数据：{...}，状态：500，状态文本：''，标题：AxiosHeaders，配置：{...}，...}堆栈：“AxiosError：请求失败，状态代码为500\n，位于settle（webpack-internal：///（app-client）/./node_modules/axios/lib/core/settle.js：24：12）\n，位于XMLHttpRequest.onloadend（webpack-internal：///（app-client）/./node_modules/axios/lib/adapters/xhr.js：121：66）"Prototype：错误

};

UPDATE*不是服务器错误，而是这里**

async function handleSubmit(event) {
    event.preventDefault();
    const url = "https://leader-board-backend.vercel.app/api/v1/score/";
    try {
      const { data } = await axios.post(url, formdata);
      dispatch(addDetails(data.name, data.exactScore));
    } catch (error) {
      console.log(error.response);
      throw error;
    }
    setFormData({ name: "", exactScore: "" });
  }

以及如何发送这些数据

const [formdata, setFormData] = useState({
    _id: "",
    name: "",
    exactScore: "",
  });

当我将每个转换为单个状态时。

const [name, setName] = useState("");
const [exactScore, setExactScore] = useState("");
function handleNameChange(event) {
    setName(event.target.value);
  }

  function handleScoreChange(event) {
    setExactScore(event.target.value);
  }

  async function handleSubmit(event) {
    event.preventDefault();
    const url = "https://leader-board-backend.vercel.app/api/v1/score/";
    try {
      const { data } = await axios.post(url, { name, exactScore });
      dispatch(addDetails(data.name, data.exactScore));
    } catch (error) {
      console.log(error.response);
      throw error;
    }
    setName("");
    setExactScore("");
  }

它工作得很好，但在其他部分（如编辑和删除）会导致错误
