I've tried with two different classes and problem still occur.

@PostMapping("/startScraping")
	public ResponseEntity<FlashScraper> startScraping(@NonNull @RequestBody FlashScraper flashScraper) throws FailingHttpStatusCodeException, MalformedURLException, IOException {
		logger.info("startScraping request incomming");
		logger.info("Call URL: " + flashScraper.getScrapeUrl());
		
	    String url = "https://flashScore.com";

	    try (final WebClient webClient = new WebClient(BrowserVersion.BEST_SUPPORTED)) {
	        HtmlPage page = webClient.getPage(url);
	        webClient.waitForBackgroundJavaScript(3_000);

	        System.out.println();
	        System.out.println();
	        System.out.println("----------------");
	        System.out.println(page.asNormalizedText());
	        System.out.println("----------------");
	    }
		
		return new ResponseEntity(flashScraper, HttpStatus.OK);
	}
