当我使用restemplate和getforobject（）方法时，我在运行spring boot时得到一个错误代码500。如何使用springboot使用这个api？

package nl.qnh.qforce.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;
import java.util.Arrays;
import java.util.List;

@RestController
public class PersonController {

    private static String url = "https://swapi.co/api/people/";

    @Autowired
    private RestTemplate restTemplate;

    @GetMapping("/people")
    public List<Object> getPeople(){
        Object[] people = restTemplate.getForObject(url, Object[].class);
        return Arrays.asList(people);
    }
}
