Github action docker/setup-buildx-action recently updated buildx default version to 0.7.1
This introduced a bug in our build pipeline.
In our action, we first run docker compose up, which creates a volume at .data/db/mysql. Then, we build the image using buildx. The new parser is trying to read this folder when loading context, even though it is ignored.
Previous output (0.7.0):
