Hope you’re well. Does the Python script work successfully when tested outside of UiPath?

Maybe checkout my blog post on getting Python working on UiPath, if you get stuck I’m more than happy to walk through debugging with you: https://thejpanda.com/2020/01/09/rpa-using-the-python-activity-in-uipath/

it’s also not working i try it the same error occurs.

Alright, if the script returns the same error outside of UiPath then the error is sitting within the Python script. What Python IDE are you using? Is it possible to debug to see exactly where the error occurs?
