How do you get GatsbyImage to work with gatsby-sanity-source?I have implemented this ( ) exactly as shown in the example, but cannot get it to work as shown.I have formatted my query exactly as shown (notice just the “asset”, without the “fluid, src, or gatsbyImage:

query vehicleQuery($slug: String) {
  sanityVehicle(id: {eq: $slug}) {
    manufacturer {
      logoimage {
However, this gives me an error on build:

GraphQLError: Field "asset" of type "SanityImageAsset" must have a selection of subfields. Did you mean "asset { ... }"?

If I add fluid, src, and even gatsbyImageData to the query:

query vehicleQuery($slug: String) {
  sanityVehicle(id: {eq: $slug}) {
    manufacturer {
      logoimage {
        asset {
          fluid {
I get a different error:

WebpackError: TypeError: Cannot read property 'split' of undefined

 ERROR #95313

A bit lost here… if I skip GatsbyImage altogether, and just use fluid src with &lt;img src.., the site builds fine, including showing images.

Here’s your graphql page query:

import React, { useEffect, useRef, useState } from 'react';
import Image from 'gatsby-image';
import './Image.scss';

const ResponsiveImage = (props) =&gt; {
  const {
    className = '',
    style = {},
  } = props;

  const [loaded, setLoaded] = useState(false);
  const imgRef = useRef();

  useEffect(() =&gt; {
    if (onLoaded &amp;&amp; imgRef.current &amp;&amp; imgRef.current.state.imgLoaded) {
  }, [imgRef.current, loaded]);

  return (
      alt={image.alt || ''}
      onLoad={() =&gt; setLoaded(true)}

export default ResponsiveImage;

You don’t need all that (eg. the onLoad handler), but its a nice little bit of functionality
