Turns:

        
text
        

            
        
     

        
text
        

            
        
     
OLE IDispatch exception code 0 from wwDotNetBridge: Invalid extension `attridbutes` from `attridbutes`"

into:

        
swift
        

            
        
     

        
swift
        

            
        
     
Invalid extension `attridbutes` from `attridbutes`"
