Hi Rebecca,
The reason of the failure can be actually spotted from this LOG.
When you check the [WARN] line, it indicates that one of your source files, specifically the “shipments_view.csv” file, contains Date (time) entry in unsupported Date format. The value is “0001-01-01 085742+005744", which is referring to year “1” .
We only support dates between the year 1900 and 2050 inclusive.
