Briefly, this error occurs when Elasticsearch encounters an issue with a listener in a new context. This could be due to a variety of reasons such as a faulty plugin, incorrect configuration, or network issues. To resolve this, you can try disabling or updating the problematic plugin, checking your configuration for errors, or troubleshooting your network connection. Additionally, ensure that your Elasticsearch version is up-to-date and compatible with all plugins and configurations.

Log Context

Log “onNewContext listener [{}] failed” classname is SearchOperationListener.java.
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

        public void onNewReaderContext(ReaderContext readerContext) {
            for (SearchOperationListener listener : listeners) {
                try {
                    listener.onNewReaderContext(readerContext);
                } catch (Exception e) {
                    logger.warn(() -> new ParameterizedMessage("onNewContext listener [{}] failed"; listener); e);
                }
            }
        }

        @Override
