gatsby: Cannot build locally after upgrade

Description

Having not worked on a client project for a few months I jumped back in for site updates, upgrading a few dependencies as instructed as well as gatsby 2.7.19 to 2.15.28.

After trying to rebuild locally after the updates I have been unsuccessful for a few hours, with the site getting stuck on the source and transform nodes process within gatsby-source-prismic when trying to download images for the news page of the site. No matter what I try, the site will not build locally.

I noticed that gatsby-source-prismic migrated to a new version of the API (v3), however applying these updates didn’t do anything, so I have reverted to the previous version.

After pushing my updates to github I have noticed that netlify persists with processing the images and builds the site, however it now takes 19 minutes to publish the site, rather than 3 minutes in previous successful build before any updates.

A few things to note…

• This is a related issue to https://github.com/angeloashmore/gatsby-source-prismic/issues/73 however the usual suggestions of “resizing the terminal” or “restarting” don’t work.

• I had previously encountered and resolved the same issue within netlify (didn’t occur locally) when pushing to build by using https://github.com/gatsbyjs/gatsby/tree/master/packages/gatsby-plugin-netlify

Thank you in advance for any help, this was my first gatsby site and I am still figuring a lot out!

Steps to reproduce

run gatsby-develop on latest deployment

You can see the project at : https://github.com/immbudden/Lanyon

Expected result

Site should generate all news images using childImageSharp and static site should be rendered

Actual result

Firstly, after all of the updates, I get the below error, which I think is unrelated but am not sure…

ERROR

(node:40989) ExperimentalWarning: The WHATWG Encoding Standard implementation is an experimental API. It should not yet be used in production applications.

Then after gatsby begins to query files from prismic…

source and transform nodes hangs around the 95% mark.

Environment

Run gatsby info --clipboard in your project directory and paste the output here.
