Uncaught TypeError: Cannot read property 'null' of undefined

[lefta]

When I open a file from the system file manager if a project is already open in Atom, I keep getting this error popping each time I change the cursor position or type in text, even after I closed the file. It is not blocking but very annoying, and the only way to get rid of this is to restart Atom.

Atom Version: 1.8.0-beta2
System: "Gentoo Base
Thrown From: json-schema package, v0.1.15
