Gitlab package registry throw 404 on npm publish

Question

I'm trying to publish a package to Gitlab package registry but it keeps erroring me with 404 @my-scope/<package-name> is not in this registry.

Initially I followed the instructions in here official docs

This is how my .npmrc looks like:

@my-scope:registry=https://gitlab.com/api/v4/projects/<project_id>/packages/npm/
//gitlab.com/api/v4/projects/<project_id>/packages/npm/:_authToken=${TOKEN}

also I've added publishConfig to package.json

  "publishConfig": {
    "@my-scope:registry": "https://gitlab.com/api/v4/projects/<project_id>/packages/npm/"
  },

When I run npm publish I keep getting 404 error as below.

npm notice Publishing to https://gitlab.com/api/v4/projects/<project_id>/packages/npm/

Your .npmrc should looks like this according to the docs:

@foo:registry=https://gitlab.example.com/api/v4/packages/npm/
//gitlab.example.com/api/v4/packages/npm/:_authToken=${MY_TOKEN}
//gitlab.example.com/api/v4/projects/<your_project_id>/packages/npm/:_authToken=${MY_TOKEN}
