Reload Linked CAD

I’m trying to reload the linked CAD from another path, but I keep getting the error:

Here is my code (I only have 1 CAD in allcadlinks just for testing out the reload method):

import clr
from Autodesk.Revit.DB import FilteredElementCollector,CADLinkType, ModelPathUtils, BuiltInParameter

doc = __revit__.ActiveUIDocument.Document

allcadlinks = list(FilteredElementCollector(doc).
                OfClass(CADLinkType).
                WhereElementIsElementType().ToElements())
for cadlink in allcadlinks:
    reloaded = cadlink.LoadFrom('C:\Users\xxx\Downloads\Drawing1.dwg')

Exception: An internal error has occurred.

Script Executor Traceback:
Autodesk.Revit.Exceptions.InternalException: An internal error has occurred.

Got the answer from another forum, forgot to put it in revit.Transaction.
