MCP - NO handler registered for notification method

[JiriValasek]

Hi, I am currently testing MCP functionalities, but I keep getting these error messages:

My testing CLI program is

@SpringBootApplication
public class Application {

	public static void main(String[] args) {
		SpringApplication.run(Application.class, args);
	}

	@Primary
	@Bean(destroyMethod = "close")
	public McpSyncClient mcpClientPuppeteer() {

		Map<String, String> envs = new HashMap<String, String>();
		envs.put("PUPPETEER_LAUNCH_OPTIONS", "{ \"headless\": false }");
		var stdioParams = ServerParameters.builder("npx")
			.args("-y", "@modelcontextprotocol/server-puppeteer")
			.env(envs)
			.build();
		var mcpClient = McpClient.sync(new StdioClientTransport(stdioParams))
			.requestTimeout(Duration.ofSeconds(60))
			.build();
		var init = mcpClient.initialize();
		return mcpClient;
	}

	@Bean
	public CommandLineRunner predefinedQuestions(ChatClient.Builder chatClientBuilder,
		McpSyncClient mcpClient, ConfigurableApplicationContext context) {

		return args -> {
			ChatClient chatClient = chatClientBuilder
				.defaultTools(new SyncMcpToolCallbackProvider(mcpClientPuppeteer()))
				.defaultAdvisors(new MessageChatMemoryAdvisor(new InMemoryChatMemory()))
				.build();

			// Question 1
			String question1 = "What is new on https://news.google.com/home? Summarize me the news"; 
			System.out.println("QUESTION: " + question1);
			System.out.println("ASSISTANT: " + chatClient.prompt(question1).call().content());

			context.close();

		};
	}
}

and I am using version 1.0.0-M6.

Does anyone know how to resolve these errors?
I've tried docs, forums, issues, stackoverflow etc. but I couldn't find any useful information.
