Invoke Python Method: One or more errors occurred

Hi Friends,

I’m trying to run a python script using UiPath. But i’m facing error “One or more errors occurred” at Invoke Python Method activity.

Attached the xaml i have developed.
PythonScript.zip (15.3 KB)

Note: I’m calling a function in python having three input parameters.

Kindly help.

Thanks,
Chandini.
