Workflow Configuration

Discussion Details

Summary

GitHub Actions workflows in our production repository have completely stopped triggering on push events, causing a critical deployment pipeline failure.

Repository Details

Repository: noops888/cf-persistent-ai-prod (private)
Issue: Workflows not triggering on push events
Duration: 5+ hours of investigation

Problem Description

GitHub Actions workflows have completely stopped triggering despite:

Valid workflow configuration (.github/workflows/ci.yml)
Actions enabled on repository
Successful git pushes to monitored branches (main, develop)
No changes to workflow files or repository settings

Evidence

Historical workflows exist: Web interface shows 106 total workflow runs
Workflow file is valid: Passes YAML validation, exists on all relevant branches
Repository Actions are enabled: Confirmed in repository settings
Git pushes succeed: No authentication or push issues
API access works: Can query workflow endpoints successfully
Multiple test commits made: All fail to trigger workflows

API Evidence:

bash$ gh api repos/noops888/cf-persistent-ai-prod/actions/runs
{
"total_count": 0,
"workflow_runs": []
}

Workflow Configuration:

yamlname: CI/CD Pipeline
on:
push:
branches: [ main, develop ]
pull_request:
branches: [ main, develop ]

Troubleshooting Performed

Repository Settings Verified:

Actions enabled ("Allow all actions and reusable workflows")
Workflow permissions configured
No branch protection blocking workflows
Repository webhooks accessible via API

File System Verification:

Workflow file exists: .github/workflows/ci.yml
File present on target branches (main, develop)
YAML syntax validation passes
File permissions correct

Authentication Testing:

GitHub CLI authenticated and functional
Git push authentication working
API access functional for other endpoints
Repository access confirmed

Event Testing:

Multiple test commits to develop branch
Commits appear in git history
No workflow runs triggered
Manual workflow dispatch not available (no workflow_dispatch trigger)

Timeline

Last successful workflow run: >19 hours ago (confirmed in web interface)
Issue discovered: ~5 hours ago

Technical Environment

Git Operations: Functioning normally
Repository Access: Normal
GitHub CLI: Functional (other commands work)
API Access: Functional (other endpoints work)
Webhook Delivery: Unable to verify, suspect failure

Previous Working State

Workflows were functioning normally >19 hours ago
106 total historical workflow runs confirm previous functionality
No configuration changes made to workflow files
No repository settings changes made

Suspected Root Cause

This appears to be a GitHub platform issue affecting webhook delivery or workflow triggering service for our repository. The combination of:

API returning zero workflow runs despite web interface showing historical runs
Complete failure of push event triggering
All troubleshooting steps exhausted
No configuration issues identified

Suggests a backend service failure or data corruption affecting our repository's webhook/workflow triggering system.

+1, same symptom here on a private repo push events completely stopped triggering (deploy.yml), zero runs since a certain commit, API/UI showing nothing at all (not even queued). Everything on my end checked out healthy (Actions enabled, workflow not disabled, YAML validated, no duplicate files, billing far from limit, linear git history, all pushes made directly by me).

Also tried forcing a resync via empty commits, no effect same as what you described here.

Hoping GitHub Support
