      Description

      A DESCRIPTION OF THE PROBLEM :
      The static method for parsing (LocalDateTime.parse) that takes in a string and DateTimeFormatter is yielding an exception
      java.time.format.DateTimeParseException: Text '20191030' could not be parsed: Unable to obtain LocalDateTime from TemporalAccessor: {},ISO resolved to 2019-10-30 of type java.time.format.Parsed

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      import java.time.*;
      import java.time.format.DateTimeFormatter;

      public class TestClass {
      String dateInput = "20201030"; // Generic input date YYYYMMDD

      LocalDateTime aDate = LocalDateTime.parse(dateInput, DateTimeFormatter.BASIC_ISO_DATE);

      //... more stuff
      }

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      A LocalDateTime of 'October 30, 2020' > > "2020-10-30T00:00"
      ACTUAL -
      java.time.format.DateTimeParseException: Text '20201030' could not be parsed: Unable to obtain LocalDateTime from TemporalAccessor: {},ISO resolved to 2020-10-30 of type java.time.format.Parsed
