Hello, 

Can you trace it and share the tracer? Or can you share a screen shot maybe? What do you mean by empty assignment, a blank screen is it?

This error usually occurs when newassignpage got deleted or newassignpage with no actions on it. please check the tracer where exactly newassignpage got initiated again even it stills exists on your assignment.

For workaround, you can copy your newassignpage to temppage before you execute your business logic and copy back to newassignpage from temppage. ( this is not the best way, but if you wanna looking for quick fix, you can apply this way)
