Unable to run Cloud Functions Task - Application Integration

[snowbrood]

I have tried to test a basic example code for Cloud Functions Task for Application Integration as provided in the documentation.

But I fail with error 

Event param is {}
Task param is {}

RuntimeError: Can not find param with key EmployeeKey

here's the code in task.py

def run(event):

  value = event.get('EmployeeKey');

  newValue = event.set('EmployeeKey' , 'XYZ');

  return

- I have already set the application integration with cloud function invoker role.

- I have already created the variable name "EmployeeName" String and variable type: None

- I have added EmployeeKey and EmployeeName as task parameter for the CloudFunction

But it still fails . Can anyone suggest how can i remedy the situation.

Thank you.
