无法通过API为Shopify文章上传图片的技术求助

我使用Golang开发，参照Shopify官方文档创建包含图片的博客文章，此前功能正常，但近期调用2022-07版本的Shopify Admin REST API时，无法为文章成功上传图片，返回的响应中没有图片URL。已尝试复制主题，问题仍未解决。以下是相关代码、请求内容及API响应，恳请协助排查：

newArticle函数代码 #

func newArticle(client *http.Client, Title string, Tags string, Body string, ImgSRC string, ImgTitle string, metaValue string, QueryURL string) *http.Response {
    pageArticle := &ArticleRequest{
        Article: Article{
            Title:       Title,
            Author:      "Hit Parader",
            Tags:        Tags,
            BodyHTML:    Body,
            PublishedAt: time.Now().UTC().Format("2006-01-02T15:04:05-0700"),
            Image: ArticleImage{
                Src: ImgSRC,
                Alt: ImgTitle,
            },
            Metafields: []ArticleMeta{
                {
                    Key:       "feature_image_page_number",
                    Value:     metaValue,
                    Type:      "single_line_text_field",
                    Namespace: "custom",
                },
            },
        },
    }

    spew.Dump(pageArticle)
    articleJSON2, err := json.Marshal(pageArticle)
    if err != nil {
        fmt.Println(err)
    }
    articleReq2, err := http.NewRequest("POST", QueryURL, bytes.NewReader(articleJSON2))
    if err != nil {
        fmt.Println(err)
    }
    articleReq2.Header.Add("X-Shopify-Access-Token", "TOKEN_HERE")
    articleReq2.Header.Add("Content-Type", "application/json")

    resp3, err := client.Do(articleReq2)
    if err != nil {
        fmt.Println(err.Error())
    }

    body, err := io.ReadAll(resp3.Body)
    if err != nil {
        fmt.Println(err)
    }

    sb := string(body)
    fmt.Println(sb)

    return resp3
}

Spew.Dump输出内容 #
