dbt-glue Handling blank values in seed files

I am trying to load a file via ‘dbt seed
The file has some blank values and looks like this:-
A,C,D
A1,B,D

I am getting a GlueCreateCsvFailed error with a message like the below:-

csv = [{“numcol”: 1.0, “textcol”: null, …

Basically blanks are getting converted to nulls in Python instead of None I guess

Can you please help here?

Thanks and Regards,
