I've developed a simple approval workflow in our SharePoint 2010 site, using a 'Assign Flexi-Task' action. It gives the below error, when it reaches the step of task creation -
Error in task. Cannot find a corresponding human workflow task id for this task.
The same error is seen if I use a 'To-do Task' or 'Request Approval' action also. Also, in some cases, it fails to start with the error 'Failed to Start retrying)'. there is neither a specifc error message of what has gone wrong, nor a corelation-id being shown. What could be the reason for such a behavior? Is it an issue from Nintex Workflow/Site-Collection/Content-DB ?
Thanks Ramses Kooijman
There might be any number of reasons, for Workflows not able to create Tasks. However, the document you have shared has good information on many possiblities.
I had the same issue.
The following article led me to the resolution.
More precisely, workflow action "Commit Pending Changes" used before the "Assign Flexi Task" was the culprit.
