Dataset Processing Difference

[JingyuanHe1222]

I was running the conversion tools by python run.py on AmazonReview 2023 data.
I reached the following two errors:

1. NameError: name 'null' is not defined when convert item data. Seemingly there are null fields in the meta json file. Any quick fixes?

2. When I diff the interaction file created by running python run.py ... ... --convert_inter with the corresponding processed interaction file provided in the Google Drive, there's a lot of difference.

Can you specify if there's any version difference between the processed dataset and the source data files used?
Thank you so much.
