TextItem.position property does not exist
I'm writing a script to export information about a document, and am encountering a strange error.
The script is inspecting an ArtLayer with a TextItem.
Below is a screenshot of the TextItem properties:

The hyphenation value is missing ("General Photoshop error...").
This item has a height value, but no width value ("General Photoshop error...").
The position property does not exist.
Does anyone know what might be causing these problems?
I can provide additional details if necessary to aid in troubleshooting.
The document is open in Photoshop CC release 20.0.4
Thanks!
