Experiencing Unexpected error value: "failed to process name-of-image.png: Response code 503 (Service Unavailable)"

Hello! I have inherited another developers gatsby-source-prismic-graphql gatsby/prismic project.

It has been a little while since I've used Gatsby and Prismic together, and I am having trouble spinning up the app locally.

After updating everything in the application, I run npx gatsby develop and I don't run into errors until
it begins to "run page queries".

After this happens I get a bunch of errors when generating image thumbnails, which are 503 errors.

Could anyone point me to anything that might be a 'gotcha' leading up to these issues on a gatsby/prismic site that hasn't been updated for about 2 years? I would really appreciate it!

Hi @ryanbrownmedia,

Thanks for reaching out.

Prismic doesn't support the gatsby-source-prismic-graphql plugin anymore, and we highly recommend you to upgrade to the new plugin that Prismic maintains.

Here is a migration guild to the new plugin
