Working though the Event Monitoring Analytics App Trailhead module, running the Trailhead Data Manager, I get the error:
An error occured in your last data refresh.
Insert failed. First exception on row 1330; first error: FIELD_INTEGRITY_EXCEPTION, Closed Date(Wed Apr 01 00:00:00 GMT 2020) in the future.: Closed Date: [ClosedDate]
Any ideas?
