Using router methods without Vue instance causes the above error. This affects unit tests with PhantomJS due to a popstate event after tests are finished. This also breaks when using the feature as intended.

Note: The line that causes the error is to ensure that asynchronous components are resolved before callbacks are executed. We can not rely on the router.app as this may not be available.

Same problem here, only working if I use v2.0.1.

I think this should be reopened. I am still getting the same error as @blake-newman when using v2.2.1. Like @ealves-pt I do not get the error if using v2.0.1

@samrose3 If that the case, can you open a new issue with a minimal repro, please?
