What causes can not write type error in a TermsQueryBuilder

TermsQueryBuilder excludeStatusQuery = QueryBuilders.termsQuery("bar", BarStatus.READY, BarStatus.DELETED); // BarStatus is an enumeration which maps to a string

java.lang.IllegalArgumentException: can not write type [class com.model.BarStatus]

Answer 1

As per my understanding, it is JSON serialization issue. You can add toString() method to both the ENUM and it will resolve issue.

TermsQueryBuilder excludeStatusQuery = QueryBuilders.termsQuery("bar", BarStatus.READY.toString(), BarStatus.DELETED.toString());
