Unexcepted Error Writing to Access File

Microsoft Access Output.0 - ERROR (version 6.0.1.0-386, build 1 from 2015-12-03 11.37.25 by buildguy) : There was an unexpected error while creating a table: java.lang.IllegalArgumentException: must have type.

Does anyone know what this means? I got this while using the Microsoft Access Output transformation.

1. All of my columns have string data types.
2. The access file is completely blank. I wanted the transformation to create/write a completely new Access file.
3. It doesn't matter if I try to write 1 row or 100,000 rows.
