ReportI have created a Custom Workflow Activity that is supposed to take a user's name from a text field called "Prepared By", match it with a user in the User entity, and convert it to a lookup. Next, I want the workflow to update the "Modified By" field. I have created a Custom Workflow Activity to try to get this to work. However, I keep receiving the following error: SandboxFault.ThrowIfGuidEmpty: entityId
Plugin Trace:

My workflow is triggered when the "Prepared By" field is updated, then I add in the custom workflow step.
Any ideas on how I can fix this error?
I haven't been able to get the workflow to actually update the "Modified By" field yet, so its possible it is a coding issue. Please see code below and let me know if there is anything I can do to update my code to fix this issue. I am fairly new to coding, so its possible I'm missing something simple.
