Code Review

This pull request adds urllib3>=2.2.2 to the requirements.txt file to address a vulnerability. The reviewer suggests pinning the dependency to an exact version (==2.2.2) rather than using >= to ensure reproducible builds and prevent potential deployment failures.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.
For more details on the timeline and next steps, please review the Help Documentation.

[gemini-code-assist]

For application deployments (such as Google App Engine), it is best practice to pin dependencies to exact versions using == rather than >=. This ensures reproducible builds and prevents unexpected deployment failures if a newer version of the library is released with breaking changes or bugs.

urllib3==2.2.2 # not directly required, pinned by Snyk to avoid a vulnerability
