Caused by: java.lang.NoSuchMethodError: 'void co.elastic.clients.transport.rest_client.RestClientTransport.<init>

UPDATE: After further investigation, I think the problem might be some incompatibility between org.springframework.boot.autoconfigure.elasticsearch.ElasticsearchClientConfigurations and the 8.9.0 RestClientTransport.
The exception is:

java.lang.NoSuchMethodError: 'void co.elastic.clients.transport.rest_client.RestClientTransport.<init>(org.elasticsearch.client.RestClient, co.elastic.clients.json.JsonpMapper, co.elastic.cl
ients.transport.TransportOptions)'
        at org.springframework.boot.autoconfigure.elasticsearch.ElasticsearchClientConfigurations$ElasticsearchTransportConfiguration.restClientTransport(ElasticsearchClientConfigurations.ja
va:90)

And digging into the code of ElasticsearchClientConfigurations:

    @Import({JacksonJsonpMapperConfiguration.class, JsonbJsonpMapperConfiguration.class, SimpleJsonpMapperConfiguration.class})
    @ConditionalOnBean({RestClient.class})
    @ConditionalOnMissingBean({ElasticsearchTransport.class})
    static class ElasticsearchTransportConfiguration {
        ElasticsearchTransportConfiguration() {
        }

        @Bean
        RestClientTransport restClientTransport(RestClient restClient, JsonpMapper jsonMapper, ObjectProvider<TransportOptions> transportOptions) {
            return new RestClientTransport(restClient, jsonMapper, (TransportOptions)transportOptions.getIfAvailable());
        }
    }

The 8.8.2 contructor of RestClientTransport is compatible with the spring boot autoconfigurer:

    public RestClientTransport(RestClient restClient, JsonpMapper mapper, @Nullable TransportOptions options)

Where as in 8.9.0 the contructor of RestClientTransport has a different contructor:

    public RestClientTransport(RestClient restClient, JsonpMapper jsonpMapper, RestClientOptions options)

As a workaround this works:

@SpringBootApplication(exclude = org.springframework.boot.autoconfigure.elasticsearch.ElasticsearchClientAutoConfiguration.class )

But I think that the solution should be by fixing the 8.9.x java client.
