#20189 Issues with buildx Issue created by kuza55 Describe the bug I am trying to use the new buildx features from source. I have a multi-stage build with a docker_image target that builds on top of a base target. With the regular builder, things work fine, but with the buildx builder, I am running into this error today:

Dockerfile:2
--------------------
   1 |     ARG BASE_IMAGE=docker/base:base
   2 | >>> FROM $BASE_IMAGE
   3 |
   4 |     RUN pip install opentelemetry-distro opentelemetry-exporter-otlp
--------------------
ERROR: failed to solve: europe-west4-docker.pkg.dev/smart-shoreline-391915/espresso-docker/base/base:0.1: failed to authorize: failed to fetch oauth token: unexpected status: 403 Forbidden

The error here is probably unrelated to pants, docker is failing to pull this image from a remote repo, however docker should not need to pull this image since it exists locally because it was just built by pants:

$ docker images
