Example 1 with BytesRestResponse

use of org.opensearch.rest.BytesRestResponse in project OpenSearch by opensearch-project.

the class RestHighLevelClient method parseResponseException.

/**
 * Converts a {@link ResponseException} obtained from the low level REST client into an {@link OpenSearchException}.
 * If a response body was returned, tries to parse it as an error returned from OpenSearch.
 * If no response body was returned or anything goes wrong while parsing the error, returns a new {@link OpenSearchStatusException}
 * that wraps the original {@link ResponseException}. The potential exception obtained while parsing is added to the returned
 * exception as a suppressed exception. This method is guaranteed to not throw any exception eventually thrown while parsing.
