Bpmn-js-nyan blank editor page when running the demo

Hello guys!

I recently cloned the bpmn-js-nyan from you guys and followed the instructions regarding building it and running, so far so good!

But when i browsed the http://localhost:9876/debug.html i only get a blank page, no editor nothing.

I double checked chrome console for errors, nothing there, no node errors either.

I believe i’m missing something.

Thanks in advance !!!

EDIT:

I found some error logs that might be useful

23 error Make sure you have the latest version of node.js and npm installed.
23 error If you do, this is most likely a problem with the bpmn-js-nyan package,
23 error not with npm itself.

23 error You can get information on how to open an issue for this project with:
23 error npm bugs bpmn-js-nyan
23 error Or if that isn’t available, you can get their info via:
23 error npm owner ls bpmn-js-nyan
23 error There is likely additional logging output above.
24 verbose exit [ 1, true ]

I fixed it via this commit.

The issue was that the nyan cat example relied on deprecated and now removed behavior.
