Instance Method Details

#coerce_exception ⇒ Object

Elasticsearch::Transport was renamed to Elastic::Transport in 8.0 This lib should support both versions that’s why we are wrapping up the transport errors to local errors.

We are not only coercing exceptions but also the response body. Elasticsearch-ruby >= 8.0 returns the response wrapped in a Elasticsearch::API::Response::Response object. We are unwrapping it to keep the same interface. But we may want to coerce it to some internal object in the future.
