GitHub Actions Errors and Fixes

Troubleshooting overview

Start by matching the exact error message, then check the technology, environment, credentials, network path, and deployment context. The pages below are grouped so you can move from broad GitHub Actions symptoms to specific root-cause families without relying on client-side search.

Evidence labels are derived at build time from each Markdown record. Source-backed entries have public URLs under a Sources checked section, while partial-source entries expose public links without a complete source block.

GitHub Actions diagnostic workflow

1. Copy the exact error signature and compare it with the page title, code block, and technology label.
2. Check whether the failure is local, CI-only, deployment-only, provider-side, or account-specific.
3. Collect non-secret versions, configuration names, request IDs, and timestamps before making changes.
4. Review source-backed or partial-source pages first when the issue might depend on provider behavior or version-specific bugs.
5. Apply the smallest reversible fix and rerun the same failing action.

Common error types

• workflow failed
• waiting for a runner
• permission denied
• secret not found
• dependency install failed
• job queued

Common causes

• Source: https://github.com/actions/toolkit/issues/2417. The downloadTool() function in @actions/tool-cache accepts arbitrary URLs without validation, enabling SSRF attacks against cloud metadata services. Medium-High severity. Affects CI/CD pipeline security for teams using custom GitHub Actions. (1 page)
• Found in actions/toolkit issue #2408 (2026-05-15). Bumping minimatch from v3 to v10 broke named export compatibility. Any GitHub Action using @actions/glob in ESM context will crash at runtime. CI/CD impact for teams using pinned actions. Category: GitHub Actions. (1 page)
• GitHub issue #2408 on actions/toolkit, created 2026-05-15. Clear root cause: PR #2355 bumped minimatch v3→v10 but internal-pattern.js still uses named import { Minimatch }. minimmate v10 doesn't export Minimatch as named export, crashing ESM contexts. Impacts any ESM-based GitHub Action using @actions/glob. Not in covered-errors.md. (1 page)
• 来源：GitHub Issues (POWERFULMOVES/PMOVES.AI#1566)。Bot 账号 github-actions[bot] 上报的定时检查发现 GH_PAT 已过期导致 pipeline 中断。这是一个通用模式：大量使用 GitHub Actions 的仓库都会面临 PAT 过期导致的部署阻塞。分类：GitHub Actions（CI/CD 失败直接影响付费团队交付）。 (1 page)
• Fetched via normal_fetch from mickeygousset.com — detailed analysis of two distinct errors when permissions scope excludes contents: read. Root cause: specifying any permissions key overrides defaults, leaving unspecified scopes at none. Public repos exempt; private/internal repos require explicit contents: read. Also affects GitHub Enterprise Cloud & Managed Users. Duplicate check against covered-errors.md: no exact match — existing entry covers generic 'permission denied publickey', this is a specific GITHUB_TOKEN scope defaulting-to-none issue unique to workflows with custom permissions blocks. (1 page)
• Found in open GitHub issue #2386 on actions/checkout repo (opened Mar 12, 2026). Persistent blocker for teams using self-hosted or container-based runners with token-authenticated repo pushes. 13+ comments, no accepted workaround. Blocking CI/CD for paying team accounts strongly impacts commercial value. Category 'GitHub Actions' is exact match. (1 page)

Safe debugging checklist

• Do not paste API keys, tokens, cookies, private repository snippets, or customer data into public issues.
• Keep a rollback path before changing credentials, billing limits, DNS, CI secrets, or production deploy settings.
• Prefer official documentation and source-backed entries over broad guesses when the error affects paid APIs or production deploys.
