Visual integrator and date fields

SOLVED

I am converting some payroll export jobs from v2017 to v2019.  In v2017, fields such as PR.PER_CHK are shown in VI as type DATE.  In v2019, the replacement field PR_PayrollHistoryHeader.CheckDate is of type STRING.

My converted job fails to export data, and I suspect it's because of a type clash in the date range criteria I've specified.  How do you handle this in v2019?
