Error On Task Assignment: Only site owners can add/delete a task RRS feed

  • Question

  • Hi,

    I'm getting a very strange error, the reason I'm calling it strange because I couldn't found a single post on this error over the web. Workflow is working fine until I use Assign a Task/ Start a Process activity. It throws the error "Only site owners can add\/delete a task", for full error message please see below:

    Following is my farm topology.

    Web Server: SharePoint 2013

    App Server: SharePoint 2013

    Workflow Server: Workflow Manager

    What I have tried:

    1. Full control permission to service account
    2. Used task assignment activities within App step
    3. Gave separate permission on the workflow task list
    4. Created a new workflow task list

    Error:

    RequestorId: b1646f10-36ce-d1c9-0000-000000000000.

    Details: An unhandled exception occurred during the execution of the workflow instance.
