On February 15th, GitHub Actions will remove support for referencing actions using the shortened version of a git commit SHA. This may cause some workflows in your repository to break. To fix these workflows, you will need to update the action reference to use the full commit SHA.
For example, if your workflow references
actions/checkout@5a4ac90, you should change it to
actions/checkout@5a4ac9002d0be2fb38bd78e4b4dbde5606d7042f. You can find the full commit SHA in the referenced action's repository.
This change is being made to align product functionality with our published security guidance
