我需要使用BigCommerce API发布一个脚本。

{
  "name": "string",
  "description": "string",
  "html": "string",
  "src": "(function (sCDN, sCDNProject, sCDNWorkspace, sCDNVers) {
    if (
      window.localStorage !== null &&
      typeof window.localStorage === 'object' &&
      typeof window.localStorage.getItem === 'function' &&
      window.sessionStorage !== null &&
      typeof window.sessionStorage === 'object' &&
      typeof window.sessionStorage.getItem === 'function'
    ) {
      sCDNVers =
        window.sessionStorage.getItem('wx_preview_version') ||
        window.localStorage.getItem('wx_preview_version') ||
        sCDNVers;
    }
    window.x= window.x|| {};
    window.x.config = window.x.config || {};
    window.x.config.frontend = window.x.config.frontend || {};
    window.x.config.frontend.cdnhost =
      sCDN + '/get/' + sCDNWorkspace + '/web/' + sCDNVers + '/';
    window.x.config.frontend.vers = sCDNVers;
    window.x.config.frontend.env = sCDNWorkspace;
    window.x.config.frontend.project = sCDNProject;
    window._wx = window._wx || [];
    var f = document.getElementsByTagName('script')[0];
    var j = document.createElement('script');
    j.async = true;
    j.src = window.x.config.frontend.cdnhost + 'sss.js';
    f.parentNode.insertBefore(j, f);
  })(
    'https://xxxx.x-x-x.mybigcommerce.com',
    'x-test-env',
    'live',
    '_'
  );",
  "auto_uninstall": true,
  "load_method": "default",
  "location": "head",
  "visibility": "storefront",
  "kind": "src",
  "api_client_id": "string",
  "consent_category": "essential",
  "enabled": true,
  "channel_id": 1
}

但它回来了
{【状态】：400，【职称】：“输入无效”，“类型”：“https://developer.bigcommerce.com/api-docs/getting-started/api-status-codes“，“错误”：{{}的}
看起来像是发生在'{' x1c 0d1x
有什么方法可以把这个脚本POST到头上吗？
