Currently, I've configured workflow manager in sharepoint server 2013 for using shareoint 2013 workflow in designer. But, while publishing the workflow, it shows following error:
System.InvalidOperationException: Operation failed with error Microsoft.Workflow.Client.WorkflowCommunicationException: The request was aborted: The request was canceled
I had registered the workflow service using:
Register-SPWorkflowService -SPSite 'http://sharepoint.example.com' -WorkflowHostUri
So, what can be the solution? Is it out of memory problem?
