[gatsby-transformer-remark] resolver html returns null

[ciokan]

I have this resolver query where I filter through all markdown entries to build a collection:

export const createResolvers = ({createResolvers}) => {
	const resolvers = {
		Query : {
			allPosts     : {
				type   : ["Post"],
				resolve: async (source, args, context, info) => {
					const { entries } = await context.nodeModel.findAll({
						type : "MarkdownRemark",
						query: {
							filter: {
								fileAbsolutePath: {regex: "//collections/posts//"}
							}
						}
					});

					return entries;
				}
			},
                }
        }
}

It returns a collection of type Post:

    type Post implements Node @dontInfer {
		id: ID!
		html: String
		rawMarkdownBody: String
		fileAbsolutePath: String
		...
	}

The MarkdownRemark entries that I select have a html field which contains the html output of the markdown file. I can see it in the Graphiql playground/console.

When I query with allPosts, the html field is empty. I get rawMarkdownBody and other fields but not html.
From what I can see html is only generated when queried for and, since I query for allPosts, my html output is never generated.

I've seen an issue where someone suggested filtering for the html field might trigger it to generate so I added a html : { ne: null } to the findAll query with no success.

Any idea how to trigger the html to be generated so I can have it available after my findAll query in the resolvers?
