GitHub push webhook payload deleted true head_commit null branch deletion
💡 Result:
When a branch is deleted, GitHub sends a push webhook event where the deleted field is set to true and the head_commit field is null [1][2]. In this scenario, the payload includes the following characteristics: - deleted: true [2] - after: 0000000000000000000000000000000000000000 (the "all-zeros" SHA indicating a deletion) [2] - head_commit: null [2] - commits: An empty array [] [2] Because the push event covers various repository changes, including branch deletions, head_commit is null because there is no remaining head commit on the reference being deleted [1][2]. If your application needs to distinguish between pushes that contain code changes and those that represent a branch deletion, you should check the deleted boolean property [1][2]. Alternatively, you can subscribe specifically to the delete webhook event if you only need to trigger logic upon branch or tag deletions, rather than all push activities [1][3].

site:docs.github.com/actions workflow syntax push branches filter branch deletion deleted true
💡 Result:
There is no specific deleted: true or similar configuration option in the GitHub Actions workflow syntax to filter for deleted branches within a push event [1][2][3]. When a branch is deleted, the push event that occurs is typically treated as an update to the repository references [3]. You cannot explicitly filter for "branch deletion" events using the on.push.branches syntax [1][3]. If you need to detect or handle branch deletions in a workflow, consider the following: 1. Understanding Push Event Behavior: When you delete a branch, the push event payload includes information about the deletion [3]. However, the workflow trigger itself operates based on the branch name patterns defined in your on.push.branches or on.push.branches-ignore configuration [1][3]. 2. Using Conditional Logic: If your workflow is triggered by a push event, you can use the if conditional at the job or step level to check the github.event.deleted property [3][4]. For example: jobs: check-deletion: runs-on: ubuntu-latest if: ${{ github.event.deleted == true }} steps: - run: echo "This branch was deleted." This approach allows the workflow to run on the push event, but restricts the execution of specific jobs or steps based on whether the event was a branch deletion [4].

🌐 Web query:
site:docs.github.com/actions expressions dereference null property github.event.head_commit.message null
💡 Result:
In GitHub Actions, attempting to access a property of a null object within an expression can lead to unexpected behavior or evaluation errors because the expression engine expects the object to exist [1]. If github.event.head_commit is null—which can occur depending on the trigger event (for example, certain pull request events or manual dispatch events may not populate head_commit)—accessing.message will fail [1]. To prevent errors when a property might be null, use a conditional check within your workflow step or job. You can verify the existence of the object before accessing its properties using the following syntax: jobs: example_job: if: ${{ github.event.head_commit!= null }} runs-on: ubuntu-latest steps: - run: echo ${{ github.event.head_commit.message }} Alternatively, you can provide a fallback value or structure your logic to avoid evaluating the expression when the data is missing [1]. Ensure that the event type triggering your workflow actually provides the expected data, as the availability of fields within the github context varies significantly based on the event that triggered the workflow [1].

site:docs.github.com webhook push payload head_commit null branch deletion
💡 Result:
When a branch is deleted via a Git push, GitHub sends a push webhook event where the head_commit field is set to null [1][2]. In the push event payload, the head_commit is defined as an object or null [1][3]. When a branch or tag is deleted, there is no "head" commit associated with the resulting state of the ref, which is why this field is null [1][2]. You can programmatically distinguish this from a standard code push by checking if the deleted boolean field in the payload is set to true [1][2]. For workflows specifically targeting branch or tag deletions, GitHub recommends using the delete webhook event, which is designed to handle these cases explicitly [1][2].

Exclude branch-deletion push events from this job.
branches: ['**'] also permits branch-deletion push events. These events set github.event.deleted to true and github.event.head_commit to null, so the notification has no commit message. Add !github.event.deleted && github.event.head_commit != null to the job condition.
