Code Review

This pull request, automatically generated by Snyk, aims to upgrade the Go version in the Dockerfile from 1.21 to 1.25.4 to fix security vulnerabilities. However, the target version 1.25.4 for the golang Docker image appears to be invalid and will likely cause the build to fail. My review includes a suggestion to use a valid, recent, and stable version of the Go image instead, and to update the accompanying comment.

[gemini-code-assist]

The proposed Go version 1.25.4 does not appear to be a valid version. The official golang Docker image does not have a 1.25.4 tag, which will cause the Docker build to fail. It's recommended to use a valid and recent version to get the security fixes, such as the latest stable version 1.22.4. The comment on line 1 should also be updated to reflect this change.

# Use the official Golang 1.22 image as the base image
FROM golang:1.22.4
