Hi All, I have a sharepoint 2013 setup on a stanalone computer, if I design a workflow solution using the Sharepoint designer it works, but if I deploy the same using Visual Studio 2012 I run into this error;

I created a SharePoint empty project and then added a Workflow item to it.

Error 2 Error occurred in deployment step 'Activate Features': System.NullReferenceException: Object reference not set to an instance of an object.   at Microsoft.SharePoint.WorkflowServices.WorkflowDefinitionStorageEventReceiver.PublishDefinition(SPItemEventProperties properties)
0 0 VSWorkflow

Yes I have tested my workflow site and its available also I have ensure my workflow is configured via the cmdlet

get-spworkflowConfig

Enviornment;

OS: Windows 2012
Sharepoin

Hi,

After you re-register the workflow using Register-SPWorkflowService , I faced same error message again. After that I open the site using SharePoint Designer and I found that my workflow is already inside the site even feature can't be activated but I can't open the workflow. Error is gone away after I delete those workflows and deploy the workflow again.

kmhsad,

thanks, your trick worked for me.

I am facing same issue. I have checked in SharePoint Designer also. It is not showing any workflow in "Workflows". Am I referring correct position in SharePoint Designer? If not where I need to see in SharePoint Designer?
