I am trying to upgrade spring data elastic search from 4.1.10 to 4.2.2
I have a date field definition like below
@Field(type = FieldType.Date, format = DateFormat.date_optional_time, index = false)
private LocalDate executionDate
It works with spring data elastic search 4.1.10 but fails in 4.2.x (4.2.0, 4.2.1, 4.2.2).
Getting the below error in bean creation of repository.
Caused by: java.lang.NullPointerException: Cannot invoke "java.lang.Class.isEnum()" because "componentType" is null
Have tried many formats.
Using the keyword "format" or "pattern" inside @Field throws this error.
Any suggestion would greatly help .
Thanks in advance.
