我在react/javascript中有以下内容：

const uploadImage = (e) => {
    e.preventDefault();

    const uploadData = async () => {

    const token = JSON.parse(localStorage.getItem('token'));

    try {
            data = await axios({
            method: 'post',
            url: 'http://192.168.1.218:8080/api/image/upload',
            data: {
                        data: base64,
                        name: 'file',
                        type: 'image/jpeg'
            },
            headers: {  "Content-Type": "multipart/form-data; boundary=<calculated when request is sent>",
                        "Authorization": `Bearer ${token}` 
                    }

        })
        } catch (error) {
            console.log(error)
        }
      }
      uploadData()
   }

但当我点击按钮时，控制台中会显示以下内容：

这个请求在 Postman 中确实有效。我尝试过添加标题，但这会导致更多错误。如果没有内容类型，则会出现500内部服务器错误。cors在后端启用。
我该怎么解决这个问题？非常感谢您的帮助。
附：这是我第一个问题。对不起，我错过了什么。
