Hello, from the available picture I can see the following problems:

- InputData of type DataTable is null
- InputString is null
- The type of InputString is Int32, maybe should be String
- The PyOutput pbject of type PythonObject is not initialized
- The Code property of the Python script is null

Please see first the following link, that may be useful:

Hope it can help. Adrian
