@Smitesh_Aher2

1. First check if the python code file is running as expected or not
2. To know the error you can open locals panel in debug mode and check the complete error

Cheers

When you are loading the script, then save the result in a variable which will be of type Python Object.

Then use the variable in the invoke where it is written instance.

InputParams: you need to pass the parameters in the order.  
Instance: Python Object, the output of the Load Python Script.  
Name: Method Name

Feel free to share py script if it doesn’t work.

@Smitesh_Aher2

can you send the py file…if all these linked are there then it should not invoke the process…liekt his should not be ther pdf\_splitter(os.path.join(folder\_path, filename))

also in parameters you need to pass `New Object() {"Path To File Here"}`

cheers
