Description

• source_conn_path: static url / directory. This helper determines whether source_conn is a file path or URL and creates the full path to the the file as needed based on the type of source_conn.

• source_conn_github: static GitHub API url / git directory. This helper determines whether source_conn is a git directory or a GitHub API creates the full path to the the file as needed based on the type of source_conn.

  A GitHub token can be configured in the "GITHUB_PAT" environment variable to avoid rate limiting.
