Issues running in Enterprise GitHub

[lnhrdt]

Our team has been using this action successfully in Public GitHub (github.com), but after migrating to a self-hosted Enterprise GitHub instance have not been able to use this action.

Whenever we use the action in our workflow:

jobs:
  some-job:

    runs-on: highcpu # our self-hosted runner

    # ...

    - uses: carvel-dev/setup-action@v2
      with:
        token: ${{ github.token }}

we get the following error (with debug logging enabled):

##[debug]Evaluating condition for step: 'Run carvel-dev/setup-action@v2'
##[debug]Evaluating: success()

The Error: Not Found log doesn't give us much to go on.

Just to rule out some troubleshooting possibilities, other popular "setup actions" work fine in our environment including:

• actions/setup-java@v4
• gradle/actions/setup-gradle@v4
• docker/setup-buildx-action@v3
• buildpacks/github-actions/setup-pack@v5.8.3

And our current workaround of creating our own action also works fine:

# .github/actions/setup-carvel/action.yml
name: Setup Carvel apps

runs:
  using: composite
  steps:
    - name: Setup imgpkg
      shell: bash
      run: |
        set -euo pipefail
        REPO=carvel-dev/imgpkg
        VERSION=$(curl -s https://api.github.com/repos/$REPO/releases/latest | jq -r .tag_name)
        echo "Installing $REPO $VERSION"

        OS=$(uname | tr '[:upper:]' '[:lower:]')
        ARCH=$(uname -m)
        if [ "$ARCH" = "x86_64" ]; then ARCH=amd64; elif [ "$ARCH" = "aarch64" ]; then ARCH=arm64; fi

        URL="https://github.com/$REPO/releases/download/$VERSION/imgpkg-${OS}-${ARCH}"
        echo "Downloading from $URL"
        curl -sSL -o imgpkg "$URL"

        chmod +x imgpkg
        mv imgpkg /usr/local/bin/

        echo
        imgpkg version

    - name: Setup kbld
      shell: bash
      run: |
        set -euo pipefail
        REPO=carvel-dev/kbld
        VERSION=$(curl -s https://api.github.com/repos/$REPO/releases/latest | jq -r .tag_name)
        echo "Installing $REPO $VERSION"

        OS=$(uname | tr '[:upper:]' '[:lower:]')
        ARCH=$(uname -m)
        if [ "$ARCH" = "x86_64" ]; then ARCH=amd64; elif [ "$ARCH" = "aarch64" ]; then ARCH=arm64; fi

        URL="https://github.com/$REPO/releases/download/$VERSION/kbld-${OS}-${ARCH}"
        echo "Downloading from $URL"
        curl -sSL -o kbld "$URL"

        chmod +x kbld
        mv kbld /usr/local/bin/

        echo
        kbld version

so we feel confident there's no networking issues from our Enterprise GitHub to the resources this action needs to download.

Any ideas?
