Security	Lock down express version to avoid unintended breaking changes from major version upgrades While upgrading express to 4.21.2 fixes security vulnerabilities, this is a major version jump from 4.8.5 that likely includes breaking changes. Review the express changelog and test thoroughly to ensure compatibility. packages/polyserve/package.json [50] -"express": "^4.21.2", +"express": "~4.21.2", Apply this suggestion Suggestion importance[1-10]: 8 Why: Using ~ instead of ^ for version pinning is important for a major version upgrade from 4.8.5 to 4.21.2, as it prevents potential breaking changes from future patch updates while still allowing security fixes.	8
