Openshift node app failed to start

问题

I am failing to start my node-based application on Openshift. The application starts OK locally but node's automatic deployment (on push to the remote master repo) hits a cyclic problem with the log;

DEBUG: Running node-supervisor with

...this loop continues indefinitely, the app reports "Started" but clearly it's failed to initialize sequelize.js.

I'm a bit lost and loosing the faith in Openshift hosting at this point. I think this might be the last straw. Any advice?

Here is my app's package.json;

I've come back to this recently and have managed to get it working by using the community built Node v0.12 cartridge. If you are having similar issues I'd recommend ditching the "official" Node v0.1 app cartridge and trying again.

Sweet - free hosting of my node app! :D
