NPM don't look for packages on GitLab Package Registry

Hi Community!

After publishing an node packages to the gitlab Package registry,I’am able to see it on gitlab package repository but when I want to install it into other project setting up the proper .npmrc using the @scope to define the registry like

@pulppo:registry=https://gitlab.com/api/v4/packages/npm/
//gitlab.com/api/v4/packages/npm/:_authToken=

NPM still hits the default repo
404 Not Found - GET https://registry.npmjs.org/@pulppo/

Am I missing something?

Thanks
Martin
