How can I echo/print the environment files of a directory/path in a Jenkinsfile during a build?

Question

In a Jenkins file, I have the following code:

#!/usr/bin/env groovy
....
def env_prod = 'prod.env'
def entrypoint = "${env.WORKSPACE}

The above is then combined like this:

${env.WORKSPACE}/$env_prod

And it is fed into a python script (through argparse); the Python script looks like:

def get_package_reference_versions(packages, env_path, env_format):
    with open(env_path) as f:
    deps = f.read()
    ....

In my Jenkins logs, I see:

    [2024-01-25T13:39:41.780Z]   File "/opt/bmll/miniconda/lib/python3.11/site-packages/something/deployment.py", line 421, in get_package_reference_versions

[2024-01-25T13:39:41.780Z]     with open(env_path) as f:

[2024-01-25T13:39:41.780Z]          ^^^^^^^^^^^^^^

[2024-01-25T13:39:41.780Z] FileNotFoundError: [Errno 2] No such file or directory: '/home/ec2-user/jenkins/workspace/pipeline-deployments/js-deployment-cr/prod.env'

Now I am trying to figure out what is inside the js-deployment-cr directory.

Is there a way to print the environment files inside the js-deployment-cr directory?

N.B. I CANNOT MAKE CHANGES IN THE PYTHON SCRIPT, because it sits in a different repository to the bash script. So I need to figure this out in the Jenkins file.
