Attribute Error and Type Error [Recipe Builder]

[DetectivePikachu]

Hi all, 

I am trying to drop some unwanted columns in Recipe Builder but I get this error from the title....any clues on why that is and how to solve it? 

When I remove the drop function  - I get another error of  "typeerror: expected sequence or array-like, got <class 'platform_sdk.dataset_reader.datasetreader'>"

Please help!
