Error in .gitlab-ci while trying to package

Question

So I'm trying to make conditions in my .gitlab-ci.yml if there is no package then, npm publish to pack the library in the GitLab registry I gave my pipeline the permission to the registry and the npm access token, but I still get the unauthorized error this is the part of the .gitlab-ci.yml where I create the .npmrc file and set the configurations.

script:
    - |
      if [[ ! -f .npmrc ]]; then
        echo 'No .nmprc found! Creating one now.'
        echo "@${CI_PROJECT_ROOT_NAMESPACE}:registry=${CI_API_V4_URL}/projects/${CI_PROJECT_ID}/packages/npm/">.npmrc
        echo "//${CI_SERVER_HOST}/api/v4/projects/${CI_PROJECT_ID}/packages/npm/:_authToken=${CI_JOB_TOKEN}">>.npmrc
        echo "//registry.npmjs.org/:_authToken=${NPM_ACCESS_TOKEN}">>.npmrc
        echo "Created the following .npmrc:"; cat .npmrc
      fi

The pipeline get me this when I try to find if there is a package with the name of : $NPM_PACKAGE_NAME

@scope:registry = "https://gitlab.example.com/api/v4/projects/project_id/packages/npm/" 
//gitlab.example.com/api/v4/projects/projet_id/packages/npm/:_authToken = (protected) 
//registry.npmjs.org/:_authToken = (protected) 
; "cli" config from command line options
long = true
$ npm config set always-auth true
$ echo $(npm view "${NPM_PACKAGE_NAME}" )
npm ERR! code E401
npm ERR! 401 Unauthorized - GET https://gitlab.example.com/api/v4/projects/project_id/packages/npm/@scope%2fmy-package

Where :

- NPM_PACKAGE_NAME=$(node -p "require('./my-package/package.json').name")

Instead of echo to the .npmrc, you could try the npm commands directly

npm config set -- '//gitlab.example.com/api/v4/projects/<your_project_id>/packages/npm/:_authToken' "${NPM_TOKEN}"
npm config set -- '//gitlab.example.com/api/v4/packages/npm/:_authToken' "${NPM_TOKEN}"

That way, you are sure the .npmrc is properly updated.
