request error (invalid_request) spring rest api - rest

Question

I wrote a Rest API using Spring boot and Rest Template .Simplest one . Here is the code that I wrote in the controller .
package wsJson;
import java.util.concurrent.atomic.AtomicLong;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
#RestController
#RequestMapping("/api")
public class RestCon {
private AtomicLong id;
public Bean b;
#RequestMapping("/bean")
public Bean getBeans(#RequestParam(value="name")String name){
return new Bean(id.incrementAndGet(), name);
}
}
Bean is simple and the main class just runs the Spring Boot App .
Whenever I run the code it runs in localhost:8080 . But as I go to the URL
http://localhost:8080/api/bean?name=User1
it gives
Request Error (invalid_request)
Your request could not be processed. Request could not be handled This
could be caused by a misconfiguration, or possibly a malformed
request.
Can anyone help me understand the problem and how to solve it?
This code works normally, but in my office I am sitting behind proxy network and this code fails like this! Does anyone have any idea why is it so!
Edit:
After I run the app , I can see after entering the controller following gets logged in console:

This has nothing to do with your spring-boot application.
If you have an exception in your application logs please let us know about the stack trace. In your code snippet id is not initialised so your code can't work:
here is an example of code i tested :
#SpringBootApplication
#RestController
#RequestMapping("/api")
public class TestApplication {
private AtomicLong id = new AtomicLong();
#RequestMapping("/bean")
public String getBeans(#RequestParam(value="name")String name){
return new Bean(id.incrementAndGet(), name).toString();
}
class Bean{
public Bean(long l, String name) {
}
}
public static void main(String[] args) {
SpringApplication.run(TestApplication.class, args);
}
}
Test your application locally without that proxy so your can be sure your application works.
You posted your app startup logs and it looks like your controller is not mapper . Maybe your controller is not scanned by the application.
You controller has to be in a sub package of the package containing the class that is annotated by #SpringBootApplication so the component scanner can see it.
