Cannot add libraries

[PixelT]

When I try to add library, I get an error in console:

app-f77aac73dd.min.js:3 TypeError: Cannot read property 'length' of undefined
    at t.e.insertImport (app-f77aac73dd.min.js:1)
    at fn (eval at compile (app-f77aac73dd.min.js:5), <anonymous>:4:351)
    at i (app-f77aac73dd.min.js:6)
    at t.$eval (app-f77aac73dd.min.js:3)
    at t.$apply (app-f77aac73dd.min.js:3)
    at HTMLAnchorElement.<anonymous> (app-f77aac73dd.min.js:6)
    at rt (app-f77aac73dd.min.js:1)
    at HTMLAnchorElement.n (app-f77aac73dd.min.js:1)

and finally the library are not added...

What library are you trying to add? What compiler are you using (LibSass, Dart, or Ruby)?

If possible, please provide a link to a gist showing this issue.

It's no matter which compiler I set, it broken in all extension which I want to add, in all type of compiler :(

Pushed an update to the app. Should be fixed now. Clear your cache and reload.
