Research direction

Open the Dockerfile and compare the Debian version in the build-stage FROM line with the distroless Python image and the accompanying comment. Align the base-image versions so they consistently target Debian 12, then verify the Docker build completes successfully.

Description

bug
What happened?

From the Dockerfile comment:

# It's important that this is Debian 12 to match the distroless image.
FROM debian:13-slim AS build
...
FROM gcr.io/distroless/python3-debian12 AS image

It looks like renovate upgraded only the first image, leaving both the comment and the second image hanging in Debian 12.

How can we reproduce it?
