Lightroom SDK: folder:getChildren() incorrectly returning 0 return values

On one of my catalogs, folder:getChildren() is returning 0 return values for a particular folder (that is, it is executing a "return;" statement, with no value):

I've optimized the catalog to no effect.

If I hide the root folder "/", then the method works correctly.

This may be related to these topics (or it may not):

Try getting the first sub-folder by path and then using that folder. That worked for me. So...

local root = catalog:getFolders()[1]
local rootName = root:getName()

local subFolder = root:getChildren()[1]
local subFolderName = subFolder:getName()

local subFolderByPath = catalog:getFolderByPath(subFolder:getPath())

local subSubFolder = subFolderByPath:getChildren()[1]
local subSubFolderName = subSubFolder:getName()
