Workflow Failure

Workflow: Auto-Triage Issues
Branch: main
Run: https://github.com/github/gh-aw/actions/runs/27086485636

Action Required

Assign this issue to an agent to debug and fix the issue.

Debug with any coding agent

Use this prompt with any coding agent (GitHub Copilot, Claude, Gemini, etc.):

Debug the agentic workflow failure using https://raw.githubusercontent.com/github/gh-aw/main/debug.md

The failed workflow run is at https://github.com/github/gh-aw/actions/runs/27086485636

Manually invoke the agent

Debug this workflow failure using your favorite Agent CLI and the agentic-workflows prompt.

• Start your agent
• Load the agentic-workflows skill from .github/skills/agentic-workflows/SKILL.md or https://github.com/github/gh-aw/blob/main/.github/skills/agentic-workflows/SKILL.md
• Type debug the agentic workflow auto-triage-issues failure in https://github.com/github/gh-aw/actions/runs/27086485636

Tip

Stop reporting this workflow as a failure

To stop a workflow from creating failure issues, set report-failure-as-issue: false in its frontmatter:

safe-outputs:
  report-failure-as-issue: false

Root cause: transient upstream HTTP 504 — no code fix required

Verdict: do NOT debug this as a code bug. This run failed because the GitHub release CDN returned HTTP 504 (Gateway Timeout) while the runner downloaded the Copilot CLI checksums. The cause is transient and external; it self-resolves on the next run.

Evidence (run 27086485636)

Failing step: Install GitHub Copilot CLI (Copilot CLI v1.0.59).

Downloading checksums from https://github.com/github/copilot-cli/releases/download/v1.0.59/SHA256SUMS.txt...
curl: (22) The requested URL returned error: 504
curl: (22) The requested URL returned error: 504
curl: (22) The requested URL returned error: 504
curl: (22) The requested URL returned error: 504
##[error]Process completed with exit code 22.

Exit code 22 = curl --fail on an HTTP >=400 response. All four retries (~5s apart, ~27s total) returned 504, so the install script aborted before the agent could start. No agent logic, MCP, or firewall fault was involved.

Classification

• Severity: P2 — transient infrastructure, single occurrence, self-resolving.
• Affected workflow / run: Auto-Triage Issues / 27086485636.
• Blast radius: isolated. No other agentic workflow in the same 6h window hit this signature (Deployment Incident Monitor was cancelled by concurrency, not failed).

Recommendation

Close on auto-expiry unless the 504 signature recurs. If Install GitHub Copilot CLI 504s appear across multiple workflows, harden actions/install_copilot_cli.sh with longer exponential backoff / more retries on the SHA256SUMS download — but a single transient 504 does not justify a code change now.

Auto-resolved — workflow recovered

Recommendation: Close. The tracked failure was transient and the workflow is healthy again.

Evidence (§27086485636 vs §27093323798):

• Failed run 27086485636 (scheduled, 2026-06-07 07:45 UTC) died with a single step_failure — Process completed with exit code 22 — at agent startup. Token usage was 0 and no real work executed, indicating a transient HTTP/network error rather than a logic defect.
• No MCP failures and no missing tools were recorded for the failed run.
• The Auto-Triage Issues workflow has since run 4 consecutive successes: §27092868757 (12:41), §27093086152 (12:51), §27093259256 (12:59), §27093323798 (13:01).
• audit-diff confirms the comparator success ran normally (19 API calls, core quota healthy). No regression, firewall, or tooling delta attributable to the failure.

No fix work is required. Reopen if exit code 22 startup failures recur on this workflow.
