NPM Scoped packages are not being proxied through artifactory
I get an error trying:

I found a closed issue with the same trouble we have. https://www.jfrog.com/jira/browse/RTFACT-10402

But the resolution does not work within our configuration.
We are running artifactory within a docker container.

I tried the resolution from Dan Kamenov but there's no change.
I still get the errors.
