Hi,
according to the API doc, It’s necessary to add an ElementFilter as argument

an example

import clr
import sys
import System
clr.AddReference('ProtoGeometry')
from Autodesk.DesignScript.Geometry import *
import Autodesk.DesignScript.Geometry as DS

#import Revit API
clr.AddReference('RevitAPI')
import Autodesk
from Autodesk.Revit.DB import *
import Autodesk.Revit.DB as DB

clr.AddReference('RevitServices')
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager
doc = DocumentManager.Instance.CurrentDBDocument

filledRegion = UnwrapElement(IN[0])

def get_DependDims(elem):
	#filterElem = ElementClassFilter(clr.GetClrType(DB.Dimension))
	# OR
	filterElem = ElementCategoryFilter(BuiltInCategory.OST_Dimensions)
	lst_dimIds = elem.GetDependentElements(filterElem)
	lst_dim = [doc.GetElement(xId) for xId in lst_dimIds]
	return lst_dim
	

OUT = get_DependDims(filledRegion)
