Sharing GitHub actions with Enterprise

Overview

The GitHub documentation suggests that actions can be shared between repositories within an enterprise. However, when I try to use an action from inside my enterprise from another repository I get the error:

Error: Unable to clone https://github.com/Org1/action refs/heads/workflow-test: repository not found

Current set up

We have two organizations Org1 and Org2 that are both in the same enterprise. Org1 contains an repository containing an action: Org1/action. Org2 contains a repository which would like to consume this action: Org2/consumer.

I have followed this documentation: https://docs.github.com/en/enterprise-cloud@latest/actions/creating-actions/sharing-actions-and-workflows-with-your-enterprise.

Org1/action

• Visibility is set to internal although it was originally private.
• I have set Settings>Actions>General>Access to Accessible from repositories in the 'ENTERPRISE NAME' enterprise

Org2/consumer

• This repository is set to allow all actions and reusable workflows.

Problem

There is no good documentation on GitHub which explains how to consume actions from within the enterprise.

This is what we currently have in Org2/consumer:

Name: Load test
on: [push]

jobs:
  run_action:
    runs-on: self-hosted
    name: Action
    steps:
      - name: Trigger Load Test
        uses: Org1/action@workflow-test # the action is on this branch
        id: action

When we run this action we get the error displayed in the Overview section. This seems like an issue with how the runner is authorizing with GitHub when pulling the repository.

I would love to know if anyone has overcome this issue, or if they have found a work around.

Thanks in advance.
