"azurerm is not a recognized provider" for Gitlab Package Regsitry

Summary

We have enabled "Gitlab Package Registry" on our Omnibus installation. When attemping to upload to the PyPI package repository we get an error:

{"message":"azurerm is not a recognized provider"}

Steps to reproduce

  1. Enabled the "Gitlab Package Registry" as described here for an omnibus installtion
  2. Settings are the following:
gitlab_rails['packages_enabled'] = true
gitlab_rails['packages_object_store_enabled'] = true
gitlab_rails['packages_object_store_remote_directory'] = "packages" # The bucket name.
gitlab_rails['packages_object_store_direct_upload'] = true         # Use Object Storage directly for uploads instead of background uploads if enabled (Default: false).
gitlab_rails['packages_object_store_background_upload'] = false      # Temporary option to limit automatic upload (Default: true).
gitlab_rails['packages_object_store_proxy_download'] = false        # Passthrough all downloads via GitLab instead of using Redirects to Object Storage.
gitlab_rails['packages_object_store_connection'] = {
        'provider' => 'AzureRM',
        'azure_storage_account_name' => '<redacted>',
        'azure_storage_access_key' => '<redacted>',
}
  1. Set up your local machine for uploading to the PyPI registry manually.
  2. Upload package via twine.
  3. Note the "400-bad request" and the error mentioned above
