Unable to execute Data Engineering Scripts in Community Edition

[Kasi]

I am getting error while executing scripts 6.1 onward with various error messages. All the earlier scripts were fine but not any more. I am not sure what is the problem and whom to contact. Multiple images are attached below from examples 6.1 and 6.2

Thanks @Kaniz Fatma​ for taking it up.

None of the scripts after 6.1 are running.

Thanks
