TL;DR: My trips.csv had invalid dates for the endDate column. "2020-15-30" is an "invalid date" (according to FromField instance for Calendar.Day) bc 15 is not a valid month (i.e. [1,12]). @dmjio helped me take a look. When we poked around the SQL, we discovered: ```sql SELECT endDate FROM TRIPS; -- shows three records SELECT date(endDate) FROM TRIPS; -- shows two records ``` |
