Troubleshoot Healthcheck Bun

  • bun.runtime is degraded: confirm the process is running in Bun, not Node.
  • Memory fields are null: the active process did not expose the expected memory API.
  • Server counters are null: your server object does not expose those optional properties.
  • No health URL exists: the package intentionally does not register routes.

Never expose runtime revision, process identity, or activity detail publicly without reviewing its sensitivity.
