I am trying to create a Collect Feedback and an Approval workflow in SharePoint 2010 Designer. I always get error occurred when permission is granted/revoked to multiple user (supplied by the user) in the workflow. When permissions are granted to a single user, the workflow functions.
First, I am setting user permissions, then starting the approval/feedback task. The error occurs while assigning permission to multiple users.
Some More details - The workflow is working on a document set with content approval and versioning enabled.
