SailsJS app on OpenShift cannot start - node.js

Question

I am new to NodeJS/SailsJS and am trying to work with OpenShift for the very first time. There could be a lot of stupid shortcomings at my end, so please keep my primitive skill level in mind.
I have a SailsJS app that is up and running on Heroku's free service. It is fully functional and in use. However, in order to try out a different, more complex platform and to explore my options, I also want to deploy it on OpenShift.
I followed some tutorials and finally managed to get my code cloned (from a private repo, I ran into some trouble providing SSH access to OpenShift) and built. The build is successful but the deployment/pod shows an error. The logs read as follows
Warning: connect.session() MemoryStore is not
designed for a production environment, as it will leak
memory, and will not scale past a single process.

I believe there are ample OpenShift professionals here to help figure this thing out. Do comment if something else needs to be shared from the code.
Thanks in advance!
