Code Review

This pull request, automatically generated by Snyk, upgrades express from 4.17.1 to 4.22.1 to address several security vulnerabilities. The upgrade is appropriate and necessary. However, the update to package-lock.json has introduced an invalid version for the lodash package, which will break the build. I've added a critical comment with a suggested fix for this issue.

The lodash package version is set to 4.17.23, which is not a valid version and does not exist on the public npm registry. This will cause npm install to fail. The latest stable version is 4.17.21. Please update the lodash entry to use a valid version. I recommend using 4.17.21 to also resolve known security vulnerabilities in older 4.17.x versions.
