Generated GitHub Workflow fails for new Phoenx app: "/rel": not found

[jc00ke]

Hi there. Here's the fly-deploy.yml that was generated by fly launch:

# See https://fly.io/docs/app-guides/continuous-deployment-with-github-actions/

name: Fly Deploy
on:
  push:
    branches:
      - main
jobs:
  deploy:
    name: Deploy app
    runs-on: ubuntu-latest
    concurrency: deploy-group    # optional: ensure only one action runs at a time
    steps:
      - uses: actions/checkout@v4
      - uses: superfly/flyctl-actions/setup-flyctl@master
      - run: flyctl deploy --remote-only
        env:
          FLY_API_TOKEN: ${{ secrets.FLY_API_TOKEN }}

Nothing out of the ordinary. When I run flyctl deploy --remote-only or fly deploy locally the build goes through fine. But when I run from an action, I get the following output for the run flyctl deploy --remote-only step:
