I have linked my GitHub repo to an OpenShift app, added the main property and start script to the package.json, but under Builds, it says "Status: Output image could not be resolved. Started: not started"
I was running into the exact same error message.  It turns out I had all my OpenShift resources in place except the ImageStream to store the build output images into.  Like @pixie recommended, try to run 
oc create imagestream <imagestream name from build config> and see if it helps with your build.
