当我仅使用一个图像查询时，为什么在GraphQL中出现重复定义错误？

Question

第一次在这里发布，但我似乎无法弄清楚。我正在用Gatsby构建一个单页应用程序，并且一直在将GraphQL与gatsby-image和gatsby-background-image结合使用。这一直很好，但是现在我收到一个GraphQL错误，说我有重复的同名查询。

我一直试图将网站部署到GitHub页面上以显示客户端，并且一直在尝试解决此错误时进行解决。我什至不知道在哪里寻找重复项。

我在pages / index.js中的查询：

export const query = graphql`
  query{
    headerGlasses: file(relativePath: { regex: "/header-glasses/" }) {
      childImageSharp {
        fluid(maxWidth: 1000) {
          ...GatsbyImageSharpFluid
        }
      }
    }
    eyeGlasses: file(relativePath: { regex: "/eyeglasses/" }) {
      childImageSharp {
        fluid(maxWidth: 1000) {
          ...GatsbyImageSharpFluid
        }
      }
    }
    headerSunglasses: file(relativePath: { regex: "/header-sunglasses/" }) {
      childImageSharp {
        fluid(maxWidth: 1000) {
          ...GatsbyImageSharpFluid
        }
      }
    }
    skiGoggles: file(relativePath: { regex: "/ski-goggles/" }) {
      childImageSharp {
        fluid(maxWidth: 1000) {
          ...GatsbyImageSharpFluid
        }
      }
    }
    showRoom: file(relativePath: { regex: "/show1/" }) {
      childImageSharp {
        fluid(maxWidth: 1000) {
          ...GatsbyImageSharpFluid
        }
      }
    }
  }

该页面之前加载良好。现在突然，我收到了这个错误：

GraphQL Error There was an error while compiling your site's GraphQL queries.
  Error: RelayParser: Encountered duplicate defintitions for one or more documents: each document must have a unique name. Duplicated documents:
- cUsersBrendCodingProjectsDiamondOpticiansSrcPagesIndexJs3730803733

我也遇到了这个错误，它似乎是由于我的几个节点模块引起的：

  

未捕获的TypeError：无法读取未定义的属性'headerGlasses'

我假设这是由于上述问题导致查询未执行的结果。
