我是 GatsbyJs - GraphQL 的新手，我一直在探索 gatsby(https://github.com/gatsbyjs/gatsby/tree/master/examples/using-gatsby-source-graphql) 提供的示例，当我尝试使用本地 apollo-grapql 服务器时，它在前端返回数据，但是它抛出了上述错误并阻止构建过程，不确定我需要在这里传递的 typeName 到底是什么？任何帮助，这将不胜感激。

    `gatsby-source-graphql`,
    {
      resolve: "gatsby-source-graphql",
     options: {
      // This type will contain remote schema Query type
      typeName: "Query",
      // This is field under which it's accessible
      fieldName: "blah",
      // Url to query from
      url: "http://10.113.34.59:4000/graphql",
      // this is URL where served exposed its service in local
  },

`gatsby-source-graphql`, <==== this caused the issue
{
  resolve: "gatsby-source-graphql",
 options: {
  // This type will contain remote schema Query type
  typeName: "Query",
  // This is field under which it's accessible
  fieldName: "blah",
  // Url to query from
  url: "http://10.113.34.59:4000/graphql",
  // this is URL where served exposed its service in local
},

下面的工作正常

{
  resolve: "gatsby-source-graphql",
 options: {
  // This type will contain remote schema Query type
  typeName: "Query",
  // This is field under which it's accessible
  fieldName: "blah",
  // Url to query from
  url: "http://10.113.34.59:4000/graphql",
  // this is URL where served exposed its service in local
 },
