Error Exporting from Symon to ICM

I have the connector set up in Symon to ICM. Simple Spreadsheet as data source in Symon with some data cleansing operations before the export tool.

The Export is set up as Export to Third Party - Varicent Incentives Connection with the Added "Record Id" column as a PK in the export.

Receiving "Unexpected error encountered while exporting to a third-party source: Unexpected error encountered during export" error with no detail in any log to investigate what is wrong.

CSV Export works just fine and I can Use a Symon Tool from the Palette in ICM to pull the export in as a calculation successfully. Just cannot go the other way to create/update a Table in ICM.
