GraphQLError: Runtime Object type "SanityImage" is not a possible type for "Image". when querying an array of images

[logansparlin]

After defining an Image interface:

interface Image implements Node {
      id: ID!
      alt: String
      _key: String
      gatsbyImageData: GatsbyImageData
      url: String
    }

and the SanityImageAsset type:

type SanityImageAsset implements Node & Image {
      id: ID
      alt: String @proxy(from: "altText")
      gatsbyImageData: GatsbyImageData
      url: String
    }

I'm able to type a single Image like image: Image @link(by: "id", from: "image.asset._ref"), however when I try and do the same for an array of images images: [Image] @link(by: "id", from: "images.asset._ref") I'm getting the error GraphQLError: Runtime Object type "SanityImage" is not a possible type for "Image".

Since it's happening at runtime and only for an array of images, I'm not really sure what the issue is but seems like a bug with the generated graphql schema from gatsby-source-sanity
