The HTTP 501 Not Implemented error means that the requested feature is not available on Bonsai. Elasticsearch offers a handful of API endpoints that are not exposed on Bonsai for security and performance reasons. You can read more about these in the [Unsupported API Endpoints](@/docs/platform/unsupported-api-endpoints/index.md) documentation.
