Can an S3 import into RDS table be forced to success using an empty file?

I am running the following script to load an S3 file into my Postgres table. When the file has data everything works as expected, however if I receive an empty file it fails. Is there anyway to override the failure, as we will expect an empty file periodically.

SELECT aws_s3.table_import_from_s3( 'exprt.invoices_all', '', '(format csv, header true)', aws_commons.create_s3_uri('exprt-S3', 'ImportFiles/INVOICES_ALL.txt', 'us-east-1') );
