[Copilot]

Key Issues Identified:

• The target Express version 4.22.0 does not exist, which will cause installation failures

@shuni The es6 example (examples/es6/package.json) also uses Express (currently version 4.21.0) but is not being updated in this security fix PR. If the security vulnerability SNYK-JS-QS-14724253 affects Express, both examples should be updated consistently to ensure the vulnerability is addressed across the entire codebase.
