I’m using a Bitbucket pipeline for deployment, I recently changed the image so the pipeline uses elixir:1.11-pipeline. This is a custom docker image but it’s working in other projects. However, now the pipeline fails at mix deps.get with this error:

mix deps.get
* Getting scrivener_html (https://github.com/goravbhootra/scrivener_html.git)
** (Mix) Error fetching/updating Git repository: the "git" executable is not available in your PATH. Please install Git on this machine or pass --no-deps-check if you want to run a previously built application on a system without Git.

Other than the image (which works in other projects) I have changed anything in the build step:

    - step: &build-backend
        name: Backend | Build
        script:
          - mix deps.get
          - mix compile
        caches:
          - elixir-build
          - elixir-deps
        artifacts:
          - deps/**
