Looks like error you are getting is related to node.js version you are using.

Could you please upgrade du package if it’s older. I can’t see the version in screenshot.

Also, please verify below

  1. Does the storage bucket exist in the same folder as the task?
    – If not, use the Storage Folder Path property.
  2. Does the user you are using have the permissions for storage buckets and uploading/updating/deleting files in the storage buckets?

Hi @Suvera_Bhanu

First, ensure that the storage bucket path you’ve provided belongs to the same folder in Orchestrator.

Next, verify that the required storage bucket permissions have been granted to the specific user..

Hope it helps!!
