Trying to understand why I'm getting this error. I only get it when I push to GitHub and our test runner attempts to run the tests.

My tests that use toBeDisabled are the only ones getting the error. Other spectator tests have worked fine for quite some time. Is there a type definition package I'm missing or something?
