Example script

    url="https://localhost:8443/hps",
    username="repuser",
    password="repuser",
    verify=False
)

project_api = ProjectApi(cl, project_id)

job = project_api.get_jobs(id=[job_id], fields=["id", "file_ids"])[0]
query_params = {"id": job.file_ids, "hash.ne": "null"}
files = project_api.get_files(**query_params)

table_data = [['Name', 'Path', 'Size',  'Last Modified']]

        f.name,
        f.evaluation_path,
