Comments suppressed due to low confidence (1)

Dockerfile:1

• The Go version '1.25rc2' does not exist. As of my knowledge cutoff in January 2025, Go versions follow the pattern 1.x.x (e.g., 1.21.0, 1.22.0). Version 1.25 would not be available yet. Consider using a stable version like golang:1.21 or golang:1.22 instead.

FROM golang:1.25rc2

[Copilot]

Using a release candidate version (rc2) in production is not recommended as it's a pre-release version that may contain bugs or breaking changes. Consider using a stable release version instead.
