I am writing a GitHub action which will detect that if any change was made to helm charts directory charts-v2/core and charts-v2/platform which has many charts in the main branch ( after a PR is merged ) .

Somehow I never get the changed charts using the below workflow

name: Release Charts to chart museaum

on:
  push:
    branches:
      - helm-autopush-charts-org
    paths:
      - 'charts-v2/**'

jobs:
  release:
    runs-on: self-hosted
    steps:
      - name: Checkout
        uses: actions/checkout@v2
        with:
          fetch-depth: 0

      - name: Get changed charts
        id: get-changed-charts
        run: |
            CHANGED_CHARTS=$(git show --format="" --name-only | xargs dirname | grep -E 'charts-v2/(core|platform)' | awk -F'/' '{print $1"/"$2"/"$3}' | sort | uniq)
            CHANGED_CHARTS=$(echo "$CHANGED_CHARTS" | tr 'n' ' ')
            echo "::set-output name=changed_charts::$CHANGED_CHARTS"
