title: TypeError: Cannot read property 'fluid' of null
body: <p>I am trying to get images from contentful data to gatsby site. I can retrieve text contents.</p>
  
  <p>I went through the <code>gatsby-image</code> plugin documentation. it looks fine.</p>
  
  <pre><code>const getBlogList = graphql`
  {
    blogs: allContentfulBlog {
      edges {
        node {
          id
          title
          image {
            fluid(maxWidth:250) {
              ...GatsbyContentfulFluid_tracedSVG
            }        
          }
        }
      }
    }
  }
  `;
  
  &lt;StaticQuery 
        query={getBlogList} 
        render={ data =&gt; {
        return({data.blogs.edges.map(({node})=&gt;{
        return(&lt;div&gt;&lt;Img fluid={node.image.fluid} /&gt;&lt;/div&gt;)
            }) 
          }
         )
        }} /&gt;
  </code></pre>
