After I installed Artifactory V5.5.1 and with one-click npm setup. I added it to my npm registry, and use npm install something, gives me Cannot read property 'replace' of null. I checked the ~/.npm/npm/underscore/ directory, it was all empty (artifactory and npm is running behind nginx, and given an internal domain)
I've tried npm v3 and v4, with both node v6 and v8
following are the logs of running npm i underscore

I was running artifactory behind a nginx, and used the confs given by artifactory docs.
It turns out 'X-Artifactory-Override-Base-Url' would mess up with npm.
It would have npm returned package zip file links in url like :// instead of http://
