        azionPersonalToken: ${{ secrets.AZION_PERSONAL_TOKEN }}
        ....

Add the Redis Database access credentials to the secrets:

    UPSTASH_REDIS_REST_URL=<value>
    UPSTASH_REDIS_REST_TOKEN=<value>
    UPSTASH_LIMIT=6
    UPSTASH_LIMIT_WINDOW=10 s // "ms" | "s" | "m" | "h" | "d";

Environments for use in the action workflow:

 - name: Create args file
    run: |
        ...
        "UPSTASH_REDIS_REST_URL": "${{ secrets.UPSTASH_REDIS_REST_URL }}",
        "UPSTASH_REDIS_REST_TOKEN": "${{ secrets.UPSTASH_REDIS_REST_TOKEN }}",
        "UPSTASH_LIMIT": "${{ secrets.UPSTASH_LIMIT }}",
        "UPSTASH_LIMIT_WINDOW": "${{ secrets.UPSTASH_LIMIT_WINDOW }}"
        ...

Note: for automatic deployment, create a pull request to the main branch.
