Gotcha. In Prefect 1.0, unfortunately, you would need to move this part into a separate task. It won’t work reliably otherwise:
@task
def get_path(folder_param):
return os.path.join(folder_param)
Perhaps this can get you a little bit more excited to slowly migrate to Prefect 2.0 You can already do that! Check this post for more details:
