CI/CD integration of Kong with Jenkins and Github Actions via Kong Deck

I am having the Kong Enterprise version running on docker. Using the local setup as well the docker image for Kong deck, I am able to reach to Kong Admin API running on my localhost:8001.
However, when I used Jenkins or Github Actions, I am getting a “permission denied” to my deck ping request.
For Github Actions I have use the following guide at Konghq portal:

Still at the ping stage I am getting an error like:

docker: Error response from daemon: OCI runtime create failed: container_linux.go:380: starting container process caused: exec: "/entrypoint.sh": permission denied: unknown.

Please help regarding this matter as I couldn’t find much resources about CI/CD on Kong over the internet.
