Are you using WDC 1.x or 2.x?
Looks like there was an attribute change... (incrementalExtractColumn vs incrementColumnId)
Can you paste sniped of your js where you read/use lastRecordNumber (or table.incrementValue)?
Thanks for the reply. I have been using the name incrementalExtractColumn. Has this been change to the other one, or is "incrementalExtractColumn" the correct one as of Tableau 9.3?
Also, I think, by this time I am seeing that parameter being sent over to the RESTful service. But I am still trying to verify some aspects of the sequence of contact between the connector and the RESTful service. If I learn anything interesting, I will post it. But this use of "datetime" as my forced type for the column seems to have helped.
