POST http://localhost:3000/api/v1/register 500 (内部服务器错误)

当我在Postman中不包含Cloudinary时，我的代码可以正常运行。但是当我在注册路由中包含Cloudinary以添加照片到账户时，我遇到了这个错误。

userAction.jsx

export const register = (userData) => async (dispatch) => {
    try {
      dispatch({ type: REGISTER_USER_REQUEST });
      const config = { headers: { "Content-Type": "multipart/form-data" } };
      const { data } = await axios.post(`/api/v1/register`, userData, config);
      dispatch({ type: REGISTER_USER_SUCCESS, payload: data.user });
    } catch (error) {
      dispatch({
        type: REGISTER_USER_FAIL,
        payload: error.response.data.message,
      });
    }
  };

            )}
        
    );
}

userController.jsx

exports.RegisterUser = catchAsyncErrors( async (req,res,next)=>{
    // const myCloud = await cloudinary.v2.uploader.upload(req.body.avatar,{
    //   folder: "avatars",
    //   width: 150,
    //   crop:"scale",
    // });
    const {name,email,password} = req.body;
    const user = await User.create({
        name,
        email,
        password,
        avatar: {
            public_id:"myCloud.public_id",
            url: "myCloud.secure_url",
        }
    });
    sendToken(user,201,res);
});

1. 我在Cloudinary上有一个ID，并导入了它的Name、API_KEY和API_SECRET
2. 后端代码在Postman上没有Cloudinary时运行良好
