Filter Media List using ContentIds

Does the $core_v2_media.List call work if you set the ContentIds property directly with a comma delimited list of GUIDs?

If that works, then start looking at your method, is $ibby_v1_Utils.GetFeaturedImageContentIds() returning the expected data?  Is the data in a comma delimited string format?

The following Velocity code is returning no results when there should be 2 records

#set($medias = $core_v2_media.List("%{ ContentIds = '871AA546-63C9-4674-879C-646F535FAC15,B3BDC50A-D92E-4DAD-BEF1-814657CCEAA9', SortBy = 'ContentIdsOrder' }"))

What am I missing?

There appears to be an error within the implementation of this combination of API options. I've logged this as:
