Thanks, Lorenzo. I'm so sorry, I misdescribed the problem, what I can't get the return value correctly is the entityType. When I am at the entity of Folder, Shot, or Milestone, the entityType return value is always a task. I try to use _context = self.session.get('Context',selection['entityId']) but the return is None. I can query the folders with session.query("Folder") but I can't catch them from event['data']['selection']

When I use to get folder, shots or milestones, the returned entityName is task. How can I read the correct entityName
