Reactjs 盖茨比映像失败的prop类型

我试着把我的WP帖子的特色图片放到帖子站点上。我遵循了教程，现在我能够在网站上看到特色图片，但我也得到了以下警告：

index.js:2177 Warning: Failed prop type: Invalid prop `fixed` supplied to `Image`.

BlogPost.js文件：

// src/templates/BlogPostTemplate.js
import React from "react"
import { graphql } from "gatsby"
import Img from "gatsby-image"
import Layout from "../components/layout"
import SEO from "../components/seo"
const BlogPostTemplate = ({ data }) => (
  <Layout>
    <SEO
      title={data.wordpressPost.title}
      description={data.wordpressPost.excerpt}
    />
    <h1>{data.wordpressPost.title}</h1>
    <p>
      Written by {data.wordpressPost.author.name} on {data.wordpressPost.date}
    </p>
    <Img
      fixed={data.wordpressPost.featured_media.localFile.childImageSharp.fixed}
      alt={data.wordpressPost.title}
      style={{ maxHeight: 450 }}
    />
    <div
      style={{ marginTop: 20 }}
      dangerouslySetInnerHTML={{ __html: data.wordpressPost.content }}
    />
  </Layout>
)
export default BlogPostTemplate
export const query = graphql`
  query($id: Int!) {
    wordpressPost(wordpress_id: { eq: $id }) {
      title
      content
      excerpt
      date(formatString: "MMMM DD, YYYY")
      author {
        name
      }
      acf {
        work_name
      }
      featured_media {
        localFile {
          childImageSharp {
            fixed(width: 300, height: 300) {
              src
              width
              height
            }
          }
        }
      }
    }
  }
`

我搜索了这类问题，似乎这不是常见的事情。希望这里有人能帮上忙。

提前谢谢

这个问题的答案是从。我用错了。它必须是这样的：

childImageSharp {
    fixed(width: 300, height: 300) {
        ...GatsbyImageSharpFixed
    }
}

childImageSharp {
    fixed(width: 300, height: 300) {
        ...GatsbyImageSharpFixed
    }
}
