Task List

• [x] Steps to reproduce provided
• [ ] Stacktrace (if present) provided
• [ ] Example that reproduces the problem uploaded to Github
• [x] Full description of the issue provided (see below)

Steps to Reproduce

1. set the property elasticsearch.defaultHeaders in the format that StringToHeaderConverter can convert
2. somehow inspect defaultHeaders in either RestClient built, or sniff http headers sent.

Expected Behaviour

The provided RestClient and the RestClient in the provided RestHighLevelClient are built with defaultHeaders filled with the values specified by the property and send requests with the headers by default.

Actual Behaviour

It does not seem to take defaultHeaders specified by the property, although the value in DefaultElasticsearchConfigurationProperties#defaultHeaders is set as expected.

Environment Information

• Operating System: macOS 11.3.1
• Micronaut Version: 2.5.1 (micronaut-elasticsearch 2.3.0)
• JDK Version: 11.0.9.1

Example Application

None.

I think this could be fixed by making DefaultElasticsearchClientFactory#restClientBuilder() configure RestClientBuilder#setDefaultHeaders() using elasticsearchConfiguration.getDefaultHeaders() as explained in the official doc.

Thank you.
