I hope to quickly learn Spring AI + ollama + deepseek r1 (local learning and deployment) through the official documentation, but when I call the interface /ai/generate based on the official documentation, I get the following error:

When I configure the following code, it can work normally.

@Configuration
public class Myconfig {
    @Bean
    public RestClient.Builder builder() {
        return RestClient.builder().requestFactory(new SimpleClientHttpRequestFactory());
    }
}

Environment

ollama version is 0.5.12
Java version: zulu 21

It might be more appropriate to add RestClient configuration near the specific content of the document, which can help beginners get feedback quickly.
