Bug: git.diff is not populated in CI on Github Actions

[Brock-Gibson]

When trying to write logic / rules around git.diff, the action is hanging and this debugging / warning i added never seems to get hit.

onGitHub {
        // Debug: Check if diff is available
        val diffContent = git.diff
        warn("DEBUG: Diff is ${if (diffContent.isNullOrEmpty()) "empty/null" else "available (${diffContent.length} chars)"}")
}

I am running in CI on Github Actions via this yml.

name: Danger

on:
  pull_request:
    types: [ synchronize, opened, reopened, edited ]

jobs:
  danger-kotlin:
    runs-on: ubuntu-latest
    name: "Run Danger"
    steps:
      - name: create app token
        uses: actions/create-github-app-token@v1
        id: app-token
        with:
          app-id: ${{ vars.DANGER_APP_ID }}
          private-key: ${{ secrets.DANGER_APP_PRIVATE_KEY }}
      - uses: actions/checkout@v4
        with:
          fetch-depth: 0
      - name: Danger
        uses: danger/kotlin@1.3.3
        with:
          dangerfile: danger/Dangerfile.df.kts
          args: --verbose
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
          DANGER_GITHUB_API_TOKEN: ${{ steps.app-token.outputs.token }}
