Question: Is there anything I need to know when converting to fcpxml timelines

I can successfully convert a kedenlive timeline to OTIO format. However converting to fcpxml results in errors. I even tried converting the otio file into fcpxml and still get the same errors. The otio file and kdenlive files open up just fine in otioview. Ca anyone help with the issue I'm having. Below is the error.

ValueError: not enough values to unpack (expected 2, got 1)

Start with opentimelineio_contrib/adapters/fcpx_xml.py, especially the conversion path through _stack_to_sequence and _frame_rate_from_element, and reproduce the otioconvert command using the reported OTIO or Kdenlive timeline. Done means the reported conversion no longer raises the shown ValueError, with the relevant behavior covered by an appropriate test.
