Description

I’m helping test a new gatsby-source-prismic plugin with @angeloashmore and am running into this error message when building my site. We are 90% sure this is related to the 6.0.0-alpha.10 version of the plugin, but we are unsure what exactly is breaking on Gatsby’s side.

3. npm run build

Expected Result

A successful build.

Actual Result

We receive the following error message:

@jared-mcc @angeloashmore I started https://github.com/gatsbyjs/gatsby/pull/36506 which seems to fix this for me on the repro you provided.

@angeloashmore @jared-mcc For now I released @next with the change ( gatsby@4.23.0-next.2) so at least you could test those things out on your end, but we will look to release this in stable next week most likely
