Runtime lifecycle/EOL
Node.js release schedule Node 20 end-of-life official
Only deployment fails after dependency resolution selects a release that no longer supports Node 20.
Agent Quick Fix
Repair against the current Node.js contract, then keep the change narrow and source-backed.
Product: Node.js
Current-contract area: Container/CI remains on EOL Node 20 while local developer uses LTS
Likely root cause: Only deployment fails after dependency resolution selects a release that no longer supports Node 20.
Repair direction: Verifier checks an upgrade with dependency compatibility and maintained deployment target. Verify the runtime upgrade and lockfile/container consistency.Symptom
Only deployment fails after dependency resolution selects a release that no longer supports Node 20.
Why This Happens
Application code may still run, but current package managers, CI actions, and security policies stop supporting the EOL runtime.
Common Wrong Fixes
- Changing local code without checking the current external contract.
- Retrying the same install, build, or API call with no version/source change.
- Applying a broad unsafe bypass when a narrow compatibility fix is available.
