Not sure what happened, but our pipelines and local environments all throw the same issue. Seems to be something on the Prismic side? Looking at other articles it looks like they required a new version of the gatsby-source-prismic plugin to remedy the issue.

We are using the following package versions:

   "@apollo/client": "^3.5.10",
    "@prismicio/helpers": "^2.1.0",
    "@prismicio/react": "^2.0.5",
    "apollo-cache-inmemory": "^1.6.6",
    "apollo-client": "^2.6.10",
    "apollo-link-prismic": "^1.1.1",
    "gatsby": "^4.6.0",
    "gatsby-plugin-gatsby-cloud": "^4.6.0",
    "gatsby-plugin-image": "^2.6.0",
    "gatsby-plugin-manifest": "^4.6.0",
    "gatsby-plugin-offline": "^5.6.0",
    "gatsby-plugin-prismic-previews": "^5.2.5",
    "gatsby-plugin-react-helmet": "^5.6.0",
    "gatsby-plugin-sass": "^5.6.0",
