OCAPI: Can't get list of content assets in "root" folder

[jwilson-lyonscg]

I'm attempting to use OCAPI to get a list of content assets in the root folder but I'm not getting results.

I'm running a GET request on /libraries/{library_id}/folders/{folder_id}/content using root as the folder_id (and of course a valid library_id). I'm not getting any content assets listed. If I use a subfolder I do get the appropriate content assets listed in that subfolder.

Is this a limitation or bug or am I doing something wrong? Anyone else able to test this and see if you get the same result?
