Greenplum Incremental '?' placeholder not working

Using ? for incremental syncs for Greenplum seem to be broken.

:information_source: The query:

SELECT * FROM "my"."dataset" WHERE last_update_time > ?

:warning: results in the 2 following errors (1 in exploration, 1 in sync):

ERROR IN EXPLORATION
-----------
ServiceException: INVALID_ARGUMENT (MagritteExplorer:SqlError): {reason=Parameter with index '0' is not specified, sqlState=HY000, vendorCode=0}
com.palantir.conjure.java.api.errors.ServiceException: ServiceException: INVALID_ARGUMENT (MagritteExplorer:SqlError): {reason=Parameter with index '0' is not specified, sqlState=HY000, vendorCode=0}

ERROR WHEN RUNNING SYNC
----------
java.sql.SQLException: Server error [SQL state: 22007]: invalid input syntax for type timestamp: "?" (Character 92)

I have tried the same sync with a real timestamp instead of the ? operator, and it runs fine.

Fixed - User Error

The fix was to explicitly enable the Incremental option in the top-right.
