Question

我正在使用gatsby，昨天一切正常，我今天继续尝试启动我的服务器并在控制台中出现大错误。我不能完全确定在哪里看，就像我昨天说的那样，它确实工作得很好。

    path: undefined } ]

我收到上述错误，通过查看我的所有文件，我只有一个地方叫productMarkdown。令我困惑的是，没有任何类别可供查找。我不确定发生了什么。运行gatsby develop时会发生此错误。

以下是查询：

productMarkdown(productId: { eq: $upperId }) {
      body
      title
      id
      titleDesc
      productInfo
      price
      active
      mainId
      cartParams {
        title
        options
      }
      extra {
        id
        title
      }
      specs {
        amount
        dimensions
      }
    }

我遇到了完全相同的问题，找不到任何错误并仔细检查了内容并使用了以下查询：http://localhost:8000/___graphql

我通过再次安装gatsby yarn add gatsby来修复它，它更新了以下软件包：

成功保存了6个新的依赖项。

├─gatsby-cli@2.4.1 ├─gatsby-link@2.0.2 ├─gatsby-plugin-page-creator@2.0.0 ├─gatsby-react-router-scroll@2.0.0 ├─gatsby@2.0.9 └─graphql-skip-limit@2.0.0

运行gatsby develop，现在可以使用与以前完全相同的代码/查询再次将字段拉细。给一个新的npm / yarn安装一下，看看是否有帮助。

GraphQLError：无法查询字段＆＃34; category＆＃34;在类型＆＃34; ProductMarkdown＆＃34;
