UnrecognizedURLError with ember-island

[adrian-fernandez]

I'm trying to use ember-cli-rails with ember-island to render components in rails views. Each time I try to include the js and css I get this error from ember:

jquery.js:3869 Uncaught UnrecognizedURLError {description: undefined, fileName: undefined, lineNumber: undefined, message: "/admin/invoices/new", name: "UnrecognizedURLError", …} (It doesn't matter the URL, it's the same with different urls).

If I run ember standalone (ember s) the app works fine, it only fails with rails.
