We have recently upgraded form AEM 6.1 to AEM 6.3. Before upgrading, we didnt purge the workflow instances. After the upgrade, we see errors in the logs where it is unable to find a specific node /etc/workflow/instances/server0/2017-10-01/wso-2choice-final_159. The node doesnt exist in AEM 6.3 anymore. However, I see that node on AEM 6.1.
I want to resolve the error in my logs "Caused by: javax.jcr.PathNotFoundException: /etc/workflow/instances/server0/2017-10-01/wso-2choice-final_159"
