Note

Medium Risk
Dependency upgrade of a core HTTP framework may introduce subtle behavior changes in request/response handling despite being a minor-version bump; changes are limited to dependency versions and lockfile regeneration.

Overview
Updates resources/solution/node.js/ex_9 to upgrade Express from 4.17.1 to 4.22.0 (Snyk-driven security bump).

Regenerates package-lock.json to align transitive dependencies with the newer Express stack (notably newer body-parser, cookie, qs, send, serve-static, http-errors, etc.), pulling in several new small utility packages used by updated deps.
