🐛 fix(loading.py): fix condition to check for "handle_keys" in format_kwargs instead of params

The condition to check for the presence of "handle_keys" has been fixed to correctly check for its existence in the format_kwargs dictionary instead of the params dictionary. This ensures that the "handle_keys" list is properly populated when necessary.
