Hm, is there a way to fix this by keeping the and not using the relative path? What's the path it's actually using?

[schulerj89]

It's just trying to get to the root directory but yarn.cmd isn't able to resolve the variable. It's the only test file that I saw that even used it this way. I also checked other areas in the code that referenced the scripts folder in the same way. It's only an issue for windows but those using windows can't run yarn test out of the box.

@rickhanlonii just keeping this on your radar.
