How to resolve NPM scoped package publish failure that result in error 405

You may receive error 405 during NPM deploy if a proxy server decodes slash(/) which is part of npm scope when npm expects to see ASCII representation of slash (%2f).

<In request.log>

When slash is decoded,

When slash is not decoded

ISSUE/RESOLUTION

Issue: Reverse proxy was decoding slash

Resolution: fix rewrite rule to not decode

• If in case of Apache, please disable the URL decoding by adding in the conf:-      

  AllowEncodedSlashes NoDecode inside <VirtualHost *:> block

•  If in case of Nginx, please add the following property to the Nginx:           

 if ( $request_uri ~ ^/artifactory/(.*)$ ) {
                     proxy_pass          http://<rproxy_artifactory>:8081/artifactory/$1;
                    }
