get_shared_links returns empty array

When I call the get_shared_links API with a path, I get back a 200 but an empty links array. So in this scenario I call create_shared_link_with_settings. This API returns a "shared links already exist" error.

I am passing in a path of /Records/paul/Births/Thompson-Hayward-20160403133425.backup and my app is EvidentiaSoftware, so I expect it to be found sinc eit exists at /Apps/EvidentiaSoftware/Records/paul/Births/Thompson-Hayward-20160403133425.backup

What am I doing wrong?

var path = "/Records/paul/Births/Thompson-Hayward-20160403133425.backup"
