package.json file in Vulnerable-OAuth-2.0-Applications/insecureapplication/gallery declares a package - array-set - as one of its dependecies. Though, the installation is aborted after the following error is thrown

4.751 npm ERR! code E404
4.754 npm ERR! 404 Not Found - GET https://registry.npmjs.org/array-set/-/array-set-0.1.2.tgz

Upon searching manually, and doing an npm search array-set, it was found out that the package, with the name array-set, doesn't exist anymore which breaks the installation.
