Custom Metabase Docker Container Issues

Recently, we were looking to deploying a docker image over to Elastic Beanstalk containing a custom Metabase version (added driver for AWS Athena support) for which the Docker image seemed to have added the custom configuration but did not show athena as an option upon running the container locally. Is there a reason as to why the running Docker container is not able to recognize the Athena code written? All of the added athena files seem to be within the running container.
