Engineering Elixir Applications - Github error when creating PR for the "Updating Your CI/CD Workflow to Include a PostgreSQL Database" section (page 149)

Ellie Fairholm @elliefairholm and Josep Giralt D’Lacoste @Gilacost,

After pushing the new branch in order to create the PR at the end of the “Updating Your CI/CD Workflow to Include a PostgreSQL Database” section, I’m getting the following error in Github during the build:

In the “Run docker/build-push-action@v5” step, the following error occurs: “Error: buildx failed with: ERROR: failed to solve: hexpm/elixir:1.16.0-erlang–debian-bullseye-20231009-slim: failed to resolve source metadata for docker.io/hexpm/elixir:1.16.0-erlang--debian-bullseye-20231009-slim: docker.io/hexpm/elixir:1.16.0-erlang--debian-bullseye-20231009-slim: not found”

Anyone else have any tips on how to get around this?
