盖茨比图像与Netlify CMSField "thumbnail"不能有选择，因为类型"String"没有子字段

Question

因为今天我面临一个问题，我不知道如何解决它。在React和Gatsby方面我是新手。发生了什么，目前我正在一个网站上工作，与netflix CMS运行。在过去的几天里，一切都很好，但是从今天开始，有些奇怪的事情发生了。我得到以下错误消息:

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":

我认为这与gatsby-remark-relative-images插件有关，但我不明白，为什么它在前几天工作而今天没有。同样奇怪的是，当我试图以编程方式创建页面并为此制作gatsby-node.js文件时，它开始了。删除该文件后，错误信息继续。我已经尝试了这里和那里的东西与我的config.yml文件，它再次工作。我再次尝试创建gatsby-node.js文件，问题又回来了。我真的不知道这是怎么回事。

下面是一些附加文件:

我知道我的描述可能在某些地方不太扎实，但我希望有人能帮助我。提前谢谢你。

Answer 1

这个问题可以有多种解决方案，这取决于导致它的原因。通常情况下，盖茨比无法创建thumbnail节点，因为它有一个不相关的类型(String)，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。

潜在解决方案:

• 执行gatsby clean:清空缓存。然后，再次执行gatsby develop。

• 检查config.yml中的media_folder和public_folder:在你的情况下，对我来说，它们看起来都很好。

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

  安装完成后。把它作为

  的一个选项

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

  之后，您需要在gatsby-node.js中包含以下代码片段:

  const { fmImagesToRelative } = require('gatsby-remark-relative-images-v2');
  exports.onCreateNode = ({ node }) => {
  fmImagesToRelative(node);
  };
  

  在您的情况下，您正在使用我建议的相同插件的v1，但您在gatsby-node.js文件中缺少先前的配置。上次我面对你的问题，v2救了我，但你可能想给一个尝试v1 +片段，如果你想。

  每次试验都要清理缓存

此外，尝试更改foreach的map循环，因为您希望在pages的每个实例中应用createPageAPI。

Answer 2

我也有这个问题，这个github问题帮助我解决了它。gatsby-remark-images (v1和v2)一直给我错误，但经过多次试验，我发现可以显式设置字段类型。这将公开所有必需的节点，您可以访问gatsbyImageData。

这是我添加到gatsby-node.js中的代码

exports.createSchemaCustomization = ({ actions }) => {
const { createTypes } = actions

createTypes(`
type MarkdownRemark implements Node {
frontmatter: Frontmatter
}
type Frontmatter {
thumbnail: File @fileByRelativePath
}
`)
}
