Node.js troubleshooting pages for runtime errors, module resolution, package loading, environment mismatches, and JavaScript project setup.
This Node.js troubleshooting hub collects real error signatures, quick fixes, common causes, and
step-by-step debugging paths for developers who need a practical answer instead of a broad overview.
3 crawlable articles in this category.
3 additional records are indexed in JSON only (no standalone HTML route).
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 Node.js 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.
Node.js diagnostic workflow
Copy the exact error signature and compare it with the page title, code block, and technology label.
Check whether the failure is local, CI-only, deployment-only, provider-side, or account-specific.
Collect non-secret versions, configuration names, request IDs, and timestamps before making changes.
Review source-backed or partial-source pages first when the issue might depend on provider behavior or version-specific bugs.
Apply the smallest reversible fix and rerun the same failing action.
Common error types
Developers building AI agent sidecars with Bun.serve find that LLM streams get cut off during reasoning phases or parallel tool-call generation when there's a >10s pause. The default 10s idleTimeout triggers a retry loop that burns through the run timeout.
appstrate/appstrate issue #426: Bun.serve uses 10s default idleTimeout. LLM streams pause during reasoning phase (>10s) → connection cut → retry loop → burns 300s run timeout. Fix: set explicit idleTimeout on Bun.serve.
GitHub Issue #4288 on modelcontextprotocol/servers (opened Jun 7, 2026). Root cause: zod declared in both dependencies and peerDependencies; with pnpm strict isolation the peer dep takes precedence but consumer does not declare zod, causing runtime ESM resolution failure. Not in covered-errors.md. Strong signal for Node.js/npm/pnpm error audience. Approved category: Node.js.
GitHub nodejs/node#63495 — precise regression identified between 24.15.0 and 24.16.0. Affects self-hosted CI runners on Linux x64/arm64. Blocks automated testing pipelines. Specific version pin points clear fix boundary.
