gatsby-source-wordpress: WP categories return undefined

[opr-inzn]

Description

There seems to be an error in the Gatsby WPGraphQL Plugin. In GraphQL under localhost:8000/___graphql I get my categories name and id returned for a post with the following query:

query MyQuery {
  wpPost(title: { regex: "/Works/" }) {
    categories {
      nodes {
        id
      }
    }
  }
}

However, in Gatsby the same query does not return anything, when I say

<p>{data.wpPost.categories.nodes.id}</p>

there is no error and the paragraph element get's rendered but without any content. I have also tried it with name, slug and basically any other of the available elements in "category" with the same result: an empty element.

Any help would be greatly appreciated!

Could you try data.wpPost.categories.nodes[0].id ?
