Getting Assemble script failed error building application in Redhat Openshift - openshift

Question

I'm new to Redhat OpenShift and trying to deploy node application (with angularjs + mysql) and running into build issues.
Using openshift console created node application and in advanced options pointed to the private repository and linked configured secret (ssh key to private repository).
My build is failing with "Assemble script failed". Pasting the logs as below (from console - obfuscated private keys and values).
Not sure if I'm missing some configurations. Appreciate help on this.

Pls note that my source code is hosted on private repository and per log above it appears openshift is able to access the repository and download the source code.

Thanks Graham for the pointer. I recreated the application and this time in advanced options on the web console selected 1 GB (from default of 500 mb) after which my build worked fine.
