From the upgrade log: Couldn't move dep contents from /var/lib/openshift/5264ecfe6cec0e38c600020d/.npm.backup to /var/lib/openshift/5264ecfe6cec0e38c600020d/.npm
I believe this has been fixed with the fix for #1020553 (https://github.com/openshift/li/commit/a89d597a6d0b02234cb5d76e19411a4f1db20e59) and/or #1024322 (https://github.com/openshift/li/commit/8a68f1ccecdbdffb578bc7c22ee0ef8e7f13987d).
If you weren't able to reproduce this in devenv 3966, I would think this will be fixed when INT is upgraded to a newer devenv.
It's also possible that app in INT is permanently busted. What we should do is:
Validate on a new devenv that it isn't a problem there.
Create apps in stage you can test this against for when stage is updated.
When INT is updated again check to see if it was fixed but don't fail this bug if it wasn't.
Verified in INT(devenv_3971) and devenv_3971 which upgraded from devenv_stage_528
Now existing nodejs app's url could be accessed.
