I have configured a dev environment with a firebase secret but I can’t write it to my .env.local file when running the ci. Only secrets in the repository globally work

jobs:

Deploy-Application:
runs-on: ubuntu-latest

steps:
    -   name: Checkout code
        uses: actions/checkout@v3

    -   name: Create .env file
        run: |
            cd /tmp/app
            touch .env.local
            echo FIREBASE_DSN=${{ secrets.FIREBASE_DSN }} >> .env.local

Thanks
