因为今天我面临一个问题，我不知道如何解决它。就 React 和 Gatsby 而言，我是个新手。发生了什么，目前我正在开发一个使用 Netlify CMS 运行的网站。在过去的几天里，一切都很好，但是从今天开始发生了一些奇怪的事情。我收到以下错误消息：

 ERROR #85922  GRAPHQL

There was an error in your GraphQL query:

      Field "thumbnail" must not have a selection since type "String" has no subfields.

      This can happen if you e.g. accidentally added { } to the field "thumbnail". If you didn't expect "thumbnail" to be of type "String" make sure that your input source and/or plugin is correct.
      However, if you expect "value" to exist, the field might be accessible in another subfield. Please try your query in GraphiQL and use the GraphiQL explorer to see which fields you can query and
what shape they have.

      It is recommended to explicitly type your GraphQL schema if you want to use optional fields. This way you don't have to add the mentioned
      "dummy content". Visit our docs to learn how you can define the schema for "undefined":

我认为它与gatsby-remark-relative-images插件有关，但我不明白，为什么它在前几天有效，而今天无效。似乎也很奇怪的是，当我尝试以编程方式创建页面并为此制作了一个gatsby-node.js文件时，它就开始了。删除该文件后，错误消息继续。我已经在这里和那里尝试过我的config.yml文件并且它再次工作。我再次尝试创建gatsby-node.js文件，问题又回来了。我真的不知道发生了什么。

以下是一些附加文件：

此问题可能有多种解决方案，具体取决于导致它的原因。通常情况下，通常发生的情况是 Gatsby 无法创建thumbnail节点，因为它有一个不相关的类型（字符串），它应该是一个图像节点，因为父子节点之间的相关性不知何故丢失了。

潜在的解决方案：

  • 运行gatsby clean：清理缓存。然后，gatsby develop又是项目。

  • 检查你的media_folder:在你的情况下，对我来说，它们看起来都不错。public_folderconfig.yml

  • 使用gatsby-remark-relative-images-v2插件：Netlify CMS 不完全支持相对路径（目前），因此在此期间，您可能需要该插件的帮助。这是因为图像位于节点文件夹之外。

    安装后。只需将其添加为

    {
    resolve: `gatsby-transformer-remark`,
    options: {
      plugins: [
        {
          resolve: `gatsby-remark-relative-images-v2`,
        },
        {
          resolve: `gatsby-remark-images`,
          options: {},
        },
      ],
    },
  },

    之后，您需要在您的 中包含以下代码段gatsby-node.js：

    const { fmImagesToRelative } = require('gatsby-remark-relative-images-v2');

exports.onCreateNode = ({ node }) => {
   fmImagesToRelative(node);
};

    在您的情况下，您使用的是我建议的同一插件的 v1，但您缺少gatsby-node.js文件中的先前配置。上次我遇到你的问题时，v2 救了我，但如果你愿意，你可能想试试 v1 + 片段。

    记得在每次试用时清理缓存。

此外，尝试更改mapa 的循环，foreach因为您想createPage在pages.

我也有这个问题，这个github问题帮我解决了。gatsby-remark-images（v1 和 v2）一直给我错误，但通过多次试验，我发现您可以显式设置字段类型。这会公开所有必需的节点，您可以访问 gatsbyImageData。

这是我添加到 gatsby-node.js 的代码

exports.createSchemaCustomization = ({ actions }) => {
    const { createTypes } = actions
  
    createTypes(`
        type MarkdownRemark implements Node {
            frontmatter: Frontmatter
        }
        type Frontmatter {
            thumbnail: File @fileByRelativePath
        }
    `)
}
