We are currently filtering out null vCPU records, we might need a small update to the filter there to prevent sending unimportant records. Trying with a real file to identify why the null filter did not filter them out correctly.

The column type for product_vcpu in the aws_line_items table is a varchar so the null value is ''. Filter needs to be updated to filter out an empty string instead of `IS NOT NULL`. Relevant code location: https://github.com/project-koku/koku/blob/main/koku/subs/trino_sql/aws_subs_summary.sql#L53
