I have an OOTB workflow (SharePoint 2013 Workflow), that works just fine. However when a user edits a task and adds an attachment, the workflow gets suspended. The users are able to view their assigned task, but if they attach a file (document), it breaks the workflow...throwing this exception:
Resume this workflow
RequestorId: d210ce4b-be17-662f-0000-000000000000. Details: An unhandled exception occurred during the execution of the workflow instance.

Clicking on the option to "Resume this workflow" still leaves it in the "suspended" state. Does anyone know why this is happening? Thanks
