axios post 请求失败，错误状态代码为 500 internalservererror

Question

我想问 对于后端火没关系。 但是当我发帖请求 500 个内部服务器

const handleChange = (e) => {
    setInfo((prev) => ({ ...prev, [e.target.id]: e.target.value }));
  };

  const handleClick = async (e) => {
    e.preventDefault();
    const data = new FormData();
    data.append("file", file);
    data.append("upload_preset", "upload");
    try {
      const uploadRes = await axios.post(
        "https://api.cloudinary.com/v1_1/dcv0xczyr/image/upload",
        data
      );

      const { url } = uploadRes.data;

      const newUser = {
        ...info,
        img: url,
      };

      await axios.post("/auth/register", newUser);
    } catch (err) {
      console.log(err);
    }
  };

POST http://localhost:3000/auth/register 500（内部服务器错误）
