Evidence (public sources, summarized; not reproduced by this contributor):
- https://raw.githubusercontent.com/puppeteer/puppeteer/main/docs/troubleshooting.md (official_docs, 2026-09, documented_behavior): Troubleshooting doc attributes this to Node < 14 or custom resolvers like jest-resolve; upgrading the resolver usually fixes it.
