If your Serverless Framework project has a dependency on a private package manager, like NPM, you will need the CI/CD service to authenticate with the private package manager service.
For example, if you are using NPM follow the "Using private packages in a CI/CD workflow" guide to create an authentication token. Following this process you will obtain a token to use as an environment variable. Other private package managers for NPM or other runtimes (e.g. Python) also typically provide a method for authentication using environment variables in a CI/CD environment.
To set an environment variable use the Parameters feature and create a variable called
NPM_TOKEN containing your private registry token. Parameters defined in the deployment profiles associated with the
application and stage are loaded in the Serverless CI/CD service as environment variables.
