Hello, Sylvain Wallez,

This is to follow up [[JAVA] Unexpected JSON event 'VALUE\_TRUE' instead of '[KEY\_NAME, VALUE\_STRING]' - #12 by swallez](https://discuss.elastic.co/t/java-unexpected-json-event-value-true-instead-of-key-name-value-string/295740/12) which was already closed.

Per [Serialize DynamicMapping values as booleans instead of string · Issue #139 · elastic/elasticsearch-java · GitHub](https://github.com/elastic/elasticsearch-java/issues/139), the issue should be fixed in 7.17.1

I recently got a chance to upgrade Elasticsearch from 7.16.3 to 7.17.3. However I am still seeing this error message following the steps described in the original link.

`Caused by: co.elastic.clients.json.JsonpMappingException: Error deserializing co.elastic.clients.elasticsearch._types.mapping.TypeMapping: co.elastic.clients.json.UnexpectedJsonEventException: Unexpected JSON event 'VALUE_TRUE' instead of '[KEY_NAME, VALUE_STRING]' (JSON path: index_templates[0].index_template.template.mappings.dynamic) (line no=1, column no=396, offset=-1)`

Can you confirm this is fixed in the version 7.17.3?

Thanks!
