A Raspberry Pi-class runner reports an unsupported Node runtime when invoking a common action.

Agent Quick Fix

The action's host runtime and runner compatibility are supplied by the CI platform, not by the repository's package.json or source tree.

Product: GitHub Actions runner
Current-contract area: ARM32 self-hosted runner loses JavaScript action support
Likely root cause: A Raspberry Pi-class runner reports an unsupported Node runtime when invoking a common action.
Repair direction: Verifier executes on the target host matrix and checks a forward-compatible action/runtime change. Check the supported runner/runtime matrix, not just a local Node invocation.

Symptom

A Raspberry Pi-class runner reports an unsupported Node runtime when invoking a common action.

Why This Happens

The action's host runtime and runner compatibility are supplied by the CI platform, not by the repository's package.json or source tree.

Verification

Verifier executes on the target host matrix and checks a forward-compatible action/runtime change. Check the supported runner/runtime matrix, not just a local Node invocation.

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.
