从WikiData获取数据时出现连接错误？

Question

我正在做一个小项目，该项目可以从Wikidata提取数据-我有几千个请求都可以正常工作，但是几天后回来，我遇到了ECONNRESET和ETIMEDOUT错误。

这是gatsbyjs的源插件，具有多个相互接续的查询-我不确定这是否是最好的方法，因此任何建议都会受到赞赏。

其链接方式：

获取parliament.uk>获取wikidata（页面ID）>获取wikidata（声明ID）>获取wikidata（声明名称）

  delete configOptions.plugins

    const nodeId = createNodeId(`mp-${
      member._about
    }`)

      id: nodeId,

    return nodeData
