The trailing comma bites! You have a new tuple.

Just venting :-(

I've just wasted a surprising amount of time on a simple mistake.

Former code:

  task = IngestTask(...,
      logical_dirpath=join(source_dir, subdir, rpath),
      ...)

During a reworking it became this:

  logical_dirpath = join(
      source_dir,
      subdir,
      rpath
  ),
  task = IngestTask(...,
      logical_dirpath=logical_dirpath,
      ...)

Typing badness ensues. In a subsequent function call far far away.
