Unable to test config files locally due to validation error

Hi @JasonTheAdams, can you try the instructions linked at the top of that Docs page?

Note: This document describes how to test and validate your config through the CircleCI API. It is also possible to install the CircleCI CLI, which allows you to validate your CircleCI config locally.

Specifically:

https://circleci.com/docs/2.0/local-cli/#run-a-job-in-a-container-on-your-machine

I think the main body of information on that Docs page is outdated, unfortunately, but running a local job with the CLI should do what you want here.

And if you don’t mind, please file an issue about these instructions on our documentation’s GitHub repository:

Thank you!
