Unable To Publish A New Package To GPR

I am currently trying out GPR using Github Actions and here is my test repo

And in that i have a workflow file named
npm-github-package.yml and it has instructions to publish a new package directly into Github Package Registry

but when i run this action it keeps failing with the below error
npm ERR! 404 Not Found - PUT https://npm.pkg.github.com/@varunsridharan%2Fvs-npm-proxy - The expected resource was not found.

i tried several diff ways and even found this https://github.com/actions/setup-node/issues/130#issuecomment-691103257

And nothing works.!!

Note i am trying to publish a new package instead of updating an existing 1. so please do guide on where i did wrong!!
