Hystrix fallback not getting called when using along with Feign

Question

I am creating a springboot application.I have 2 applications Producer and Consumer. I am using Hystrix and Feign together. When I am calling wrong producer endpoint then fallback is not executing instead it is giving 404 path not found exception. Please help

Here is the code snippet

Producer

bootstrap.properties

spring.application.name=cst-employee-producer

PizzaController.java

@RestController
public class PizzaController {

    @Autowired
    private Environment environment;
    
    private static Map<Integer, PizzaOrderEntity> mapOfPizzas = new LinkedHashMap<Integer, PizzaOrderEntity>();
    static{
        mapOfPizzas.put(10001, new PizzaOrderEntity(101,"Farm House1",5,467.54,"7905947915"));
        mapOfPizzas.put(10002, new PizzaOrderEntity(102,"Farm House2",6,567.54,"7905947916"));
        mapOfPizzas.put(10003, new PizzaOrderEntity(103,"Farm House3",7,667.54,"7905947917"));
    }
    
    @RequestMapping(value = "/producer/getPizzaDetails", method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_VALUE)
    public ResponseEntity<Collection<PizzaOrderEntity>> getEmployeeDetails() {
        Collection<PizzaOrderEntity> pizzaList = mapOfPizzas.values();
        System.out.println("I am server with port number "+environment.getProperty("server.port")+". I am hit");
        return new ResponseEntity<Collection<PizzaOrderEntity>>(pizzaList, HttpStatus.OK);
    }
}
