Cannot build images in parallel using

[isarns]

Description

When attempting to build images in parallel using the append-buildx-action@v1, the process fails. The expected behavior is to have multiple images building concurrently to decrease the overall build time.

Steps to Reproduce

1. Set up a GitHub Actions workflow with append-buildx-action@v1.
2. Configure the workflow to build multiple images in parallel.
3. Trigger the workflow.

Expected Behavior

The images should be built in parallel, minimizing the total build time.

Actual Behavior

The build process for images does not run in parallel. Instead, it causes a failure or conflict, as indicated in the attached screenshot

Workaround

As a temporary solution, I've configured the workflow to build images in sequence, which is successful but not optimal due to the increased build time.

Maybe the problem is that both jobs are using the same "builder name"? Could you try to choose different names to see if this solves the issue?

      - name: "Set up Docker Buildx"
        id: builder-backend
        uses: docker/setup-buildx-action@v1

and

      - name: "Set up Docker Buildx"
        id: builder-frontend
        uses: docker/setup-buildx-action@v1

Sorry for the delay, tried it but it didn't help, same issue.
