I have created one option called Activation(Emergency and Timed WF) in the Workflow.When I select that option in sidekick under workflow and click start workflow it should activate my content page,but it is throwing pop-up like org.apache.sling.api.slingException ,No Authorizable with ID null.And I have also checked in the error.log,I am getting the below error,
ERROR* [172.27.66.128  GET /libs/cq/workflow/content/console/process.list.json HTTP/1.1] com.adobe.granite.workflow.console.servlet.ProcessListServlet trouble resolving jcr:title property form script's jcr:content node. Fallback to script path.
Suggest some answer please.
Let us know if you are using OOTB workflow or any custom workflow to achieve the activation. Also ensure that that the user has sufficient permission to initiate or take action on workflow.
