Code Review

This pull request, automatically generated by Snyk, upgrades the winston dependency to resolve a security vulnerability. However, this upgrade introduces a critical issue. The new version of winston and its transitive dependencies require a newer Node.js runtime (v12+, and even v20+ for some packages) than what the project appears to be using (Node.js 10, based on @types/node). Merging this change without upgrading the Node.js environment will likely break the application.

critical

This upgrade to winston@3.19.0 requires Node.js v12 or newer. The project's @types/node dependency suggests it targets Node.js 10, making this a breaking change. Additionally, the updated package-lock.json brings in other dependencies that require Node.js v20 or newer. Before merging, the Node.js runtime environment for this project must be upgraded to be compatible with these new dependency requirements to avoid breaking the application.
