我试图弄清楚如何Neoj 4桌面可以用来处理NLP usgin这个blog.一切都很好，直到文本分类的时刻：

CALL apoc.periodic.iterate("
// get all articles
   MATCH (node:Article) RETURN node
  ","
   // classify each article
   CALL apoc.nlp.gcp.classify.graph(node, {
       // we retrieve gcp api key from static value storage
       key: apoc.static.get('gcp.apiKey'),
       // node property that contains the text
       nodeProperty: 'content',
       write:true
    }) YIELD graph RETURN distinct 'done'",
    {batchSize:10})

它不会返回类别，而是返回“The requested URL /v1/documents：classifyText？key=apiKey was not found on this server”（在此服务器上找不到请求的URL/v1/documents：classifyText？key=apiKey）错误
也许这是与GCP证书的东西，但我已经做了一切建议。
