Updating the local eslint fixed the issue. I just guessed and that fixed it. It would be better if it somehow could gracefully encourage the right version of eslint.

That particular error was fixed in ESLint v3.5.0.

The message you saw is a generic message thrown whenever an invalid coordinate is given from ESLint, as that (should) indicate a problem in what ESLint is telling you, we aren't filtering it out. We also can't really make it tell you the "right version" as that is almost always the latest version, and we would have to start building up a database of known bugs in ESLint and when they were fixed.
