VB node not working in loaded cluster in python

I have a cluster in GH for uploading and downloading files from server via FTP using VB code . The cluster is working fine as long as it is loaded in GH directly from the canvas .However , if I loaded the same cluster in Ghpython from local path it is not working .

I attached the cluster Ghpython code for loading cluster from path and the FTP cluster as well .

Any advise on this matter .
