Currently blocked by:

I believe if you re-run these actions, it will pass.

Strangely enough I don't have option to rerun.

phpspec's now at least running but I'm not familiar enough with the tool to fix the failures.

It's better in kbond#1, but still have:

/bin/tools/phpspec/vendor/bin/phpspec ru

  21  - it generates route collection one as is and one with locale prefixed route
      exception [err:TypeError("Double\Symfony\Component\Routing\Route\P3::getPath(): Return value must be of type string, null returned")] has been thrown.

It highly depends on the version, so it's hard to cover all cases.
