Spring Boot + React - błąd 500 tylko przy GET

Mam następujący problem: od pewnego czasu próbuję (zaznaczam od razu, że się uczę, więc dopiero szukam tej właściwej drogi..) połączyć moją aplikację Spring Boot z Reactem. Ogólnie kilka małych sukcesów już jest, ale mam ogromny problem z pobraniem danych z bazy danych.

Szukałem rozwiązań tego problemu i znalazłem taki przykład połączenia Springa z Reactem: https://bezkoder.com/react-spring-boot-crud/

Na początek chciałem przerobić ten kod na moje potrzeby, ale ponieważ ciągle pojawiały się różne błędy, postanowiłem najpierw przetestować działanie kodu opisanego na stronie z linka. Skopiowałem wszystko jak jest opisane w artykule i zadziałało pięknie, każda pojedyncza metoda.

Wróciłem zatem do mojej aplikacji, ale mimo licznych prób nie osiągnąłem zamierzonego celu. Odpaliłem więc ponownie aplikację z powyższego artykułu i.. przestał działać GET, choć działają wszystkie pozostałe żądania. Nic nie zmieniłem w kodzie, mało tego, na wszelki wypadek jeszcze raz skopiowałem wszystko ze strony, ale nadal pojawia się komunikat:

Error: Request failed with status code 500
at createError (createError.js:16)
at settle (settle.js:18)
at XMLHttpRequest.handleLoad (xhr.js:59)

Ma ktoś wskazówkę, co zrobić, aby to przełamać? Tkwię w miejscu z tym błędem już od 2 dni..

No dobra dostajesz tą 500 we froncie, ale przecież ona idzie z backendu o_O To zobacz moze w logi bakendu co się wywaliło. Bo teraz to troche tak jakby paliła ci się kontrolka check engine w samochodzie i próbujesz coś na podstawie tej kontrolki wymyślić, a tu trzeba zajrzeć pod maskę.

Od startu aplikacji, przez wyświetlenie błędu na froncie:

Ok, dopatrzyłem się więcej..

@luke83 lepiej ale to nadal nie są dobre logi. Znając życie to odpalasz tą aplikacje w taki sposób, ze wartościowe logi idą w piach. Jak to uruchamiasz?

Tak trochę na marginesie, to nie wiem czy bym się uczył z tego tutoriala ;] Jak widzę:

        if (tutorialData.isPresent()) {
            return new ResponseEntity<>(tutorialData.get(), HttpStatus.OK);
        } else {
            return new ResponseEntity<>(HttpStatus.NOT_FOUND);
        }

To wiem ze autor nie umie w Springa, a w Javę też tak średnio.
Tak samo cała logika upchnięta do kontrolera :/ widać ze ktoś nic ponad tutorial chyba w życiu nie napisał.

W logach nic nie masz bo w controlerze wyłapujesz wyjątek i zwracasz Response z 500:

        try {
            List<Tutorial> tutorials = new ArrayList<Tutorial>();

            if (title == null)
                tutorialRepository.findAll().forEach(tutorials::add);
            else
                tutorialRepository.findByTitleContaining(title).forEach(tutorials::add);

            if (tutorials.isEmpty()) {
                return new ResponseEntity<>(HttpStatus.NO_CONTENT);
            }

            return new ResponseEntity<>(tutorials, HttpStatus.OK);
        } catch (Exception e) {
            return new ResponseEntity<>(null, HttpStatus.INTERNAL_SERVER_ERROR);
        }

Najprościej w catchu daj:

e.printStackTrace()

I wrzuć kod błędu.

I to tutaj, jesli w ogóle, będą pojawiać się błędy (o ile nie będziesz ich "zjadać", patrz wyżej).

Dzięki za wskazówki - spróbuję powalczyć znowu wieczorem ;)

Dziękuję wszystkim za pomoc :) Zmieniłem w controllerze catcha zgodnie z poradą @Aisekai i pojawił się właściwy błąd, a mianowicie dla tabeli Tutorials w kolumnie Published były nulle, natomiast Published jest typu String. Zamieniłem więc typ kolumny i wszystko działa pięknie :)
Jeszcze raz dzięki :)
