Create PDF Smart Service Activity Class Error

I have been trying to get the Create PDF Smart Service to run but keep running into the same error, no matter how I configure the inputs of the node. The error I am getting is

An error occurred in executing an Activity Class.

This solution did not work and we get the same Activity Class Error as one of the replies on the post.

I have tried configuring the node in many different ways to try and solve the error but the below is the configuration that makes the most sense to me which still returned the above error:

INPUTS:

Create New Document: True

New Document Name: "Test_"&now()&".pdf"

New Document Desc: null,

Save In Folder: Folder referenced by an constant

Existing Document: null,

Document: null,

Pause On Error: false,

        }      
      )    
    }  
  )
