Not sure if the updated version of eslint-plugin-node called eslint-plugin-n would catch this or not.

It was a combination of things that caused this to happen. The unit tests would normally have caught this because they run on all node versions, but something in the switch from jest to vitest may cause it run differently.

Also a simple smoke test would have gotten this, but node 14 was dropped in favor of 19.
