Next column values not displaying using a!hierarchyBrowserFieldColumns

Hello,

I am trying to display the next column values using a!hierarchyBrowserFieldColumns, but I am getting the below error

Interface Definition: Expression evaluation error at function a!hierarchyBrowserFieldColumns [line 27]: Error in a!forEach() expression during iteration 1: Expression evaluation error at function a!hierarchyBrowserFieldColumns_buildMainPathNode [line 127]: A columns browser component [label=“”] has an invalid value for “nodeConfigs” when fv!nodeValue is . “nodeConfigs” must not have a null value for “id”.

sample code:

load(
local!jsonResponse:{
'type!{urn:com:appian:types:folders}CMN_folderJSON'( objectId: "1", objectName: "Application", parentId: "1", objectType: "dm_folder", level:"1"),

},
local!path,
local!selection,

),
{}
),
pathValue: local!path,

a!forEach(
items: local!caseDocumentsOutputFolder,
expression: if(local!caseDocumentsFolder=fv!item.parentId,fv!item,{} )
)
)
),{}
)
)
)

I need to show the UI as below

Here O: objectId and P: parentId

For next column, the condition is the next column nodes (Test ParentId:1) parentId should be mapped to the objectId of previous level node (Application objectId:1).

Please help........

Thanks in advance
