We are seeing issues in publishing/ saving Nintex workflows for a particular user.
logs showing details:
Error saving from workflow export file.: System.NullReferenceException: Object reference not set to an instance of an object.
at Nintex.Workflow.Publishing.Publish.SaveAWorkflow(String wfName, NWActionConfigurations configs, Guid listId, SPWeb web, ImportContext importCtx, SPContentTypeId contentTypeId, String changeNotes)
at NintexWorkflowWS.SaveWorkflow(String wfName, String activityConfigs, Guid listId, String contentTypeId, String changeNotes) (Build:3210)
We tried editing an existing workflow created by another user which is working fine for her. But when she tries to create a workflow on her own, not able to save / publish the workflow though she is using single Send Email action.
