从 React 向 Mongodb 发送数据时出现 422（无法处理的实体）错误

当我通过 Node.js 将表单数据从 React 发送到 Mongo DB 时出现

422 (Unprocessable Entity)

虽然我试过了

 "proxy": {
    "/signup": {
      "target": "http://localhost:5000",
      "secure": false
    }
  },

(server is running on 5000 and client is on 3000)

还是不行？ 这是发送数据的代码

const registerData = async (e) => {
        e.preventDefault();
        const { name, email, phone, work, password, cpassword } = user;

        const response = await fetch('/signup', {
            method: "POST",
            headers: {
                "Content-Type": "application/json"
            },
            body: JSON.stringify({
                name, email, phone, work, password, cpassword
            })
        });

        const data = await response.json();

        if (data.status === 422 || !data) {
            window.alert("Invalid Registration");
            console.log("Invalid Registration");
        }
        else {
            window.alert("Registration Successful");
            console.log("Registration Successful");
        }


    };

我想成功地将表单数据发送到数据库并注册用户然后使用该凭据登录
