Why is outgoing log not generated in the log folder in the NPCI GST portal?

Outgoing log is generated from approximately 2 hours from placing the invoices and the excel files in the Outgoing folder in the NPCI GST portal. The contents of the excel file should match with that of the pdf invoices placed. There should not be any extra columns, rows, or formulas in the excel file placed.
