Hello @brian_satijadi

If you remove the CSV parsing is it working?
I think after reading a csv it will be in datatable format. whereas Generate Datatable can be used to convert string to datatable using some delimiter.

Hi @brian_satijadi, I hope you are doing well.

This problem occurs because of various reasons:
1)Firstly, there is one more CsvHelper package in IntelligentOCR.
2)Secondly, this problem only occurs in the 4.9-preview version. If you downgrade to 4.8-preview you will be able to use CSV methods. Also, you can downgrade to stable versions but probably some activities are fine.
3)Thirdly, I suggest you should upgrade package ‘uipath.system.activities’ that contains CsvHelper.

Just check if any one of the 3 helps to solve your problem.

Thanks & Regards,
