Fallback method not being called by @HystrixCommand annotation

Question

fallback method mentioned in @HystrixCommand is not being called in case a downstream service is down. I am using spring boot version 3. I am not sure what I am missing here.

@SpringBootApplication

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

}

@HystrixCommand(fallbackMethod = "getFallbackCatalog")
    public List<CatalogItem> getCatalog(String userId) {

        UserRating userRating = restTemplate.getForObject("http://ratings-data-service/ratingsdata/user/{userId}",
                UserRating.class, userId);

        return userRating.getRatings().stream().map(rating -> {
            Map<String, String> param = new HashMap<>();
            param.put("movieId", rating.getMovieId());
            
            Movie movie = restTemplate.getForObject("http://movie-info-service/movies/{movieId}", Movie.class,
                    rating.getMovieId());
            return new CatalogItem(movie.getName(), "description", rating.getRating());
        }).collect(Collectors.toList());
    }

//Fall back method

    private List<CatalogItem> getFallbackCatalog(@PathVariable("userId") String userId){
        return Arrays.asList(new CatalogItem("No movie", "", 0));
    }

If movie-info-service is down, call should come to getFallbackCatalog instead it is throwing error saying movie-info-service is not available.
