Problem description

While trying to create a new index using the Elastic Java Client API, I stumble across the following exception:

Error deserializing co.elastic.clients.elasticsearch._types.analysis.HtmlStripCharFilter: Unknown field 'escaped_tags' (JSON path: settings.index.analysis.char_filter.html_body_filter.escaped_tags)

Code:

public void createIndex(String index, String settingsJson) throws IOException { LOG.info("Creating index {}", index); CreateIndexRequest request = new CreateIndexRequest.Builder() .index(index) .withJson(new StringReader(settingsJson)) .build(); elasticsearchClient.indices().create(request); } 

where the settings json contains the following:

... "char_filter": { "html_body_filter": { "type": "html_strip", "escaped_tags": [ "body" ] } } ... 

According to the documentation, this is a valid configurable parameter.
