Output Data Error: WKB structure does not match expected size

[Fairly]

I'm running a workflow where I am sending data to a PostgreSQL database that has Postgis in it. However, when it tries to write the data to the database, I am getting an error saying:

Output Data (18) DataWrap2ODBC::SendBatch: ERROR: WKB structure does not match expected size!;¶Error while executing the query Insert into "table_name"("column_1","column_2","column_3","geom") Values (?,?,?,ST_GeomFromWKB(?,4326))

I thought it might be the Spatial Object Field Size but when I increased it, it didn't do anything. Does anybody know why I am getting this error and how to fix it?
