    private FrageTyp frageTyp;
    private int antwortzeitSekunden;
}

public class Antwort {
    private String antwort;
    private Integer karteikarte;
}

public interface KarteikartenSetDao extends CrudRepository<KarteikartenSetDto, Integer> {
    List<KarteikartenSetDto> findAll();
    
}

public class KarteikarteSet

Spring Boot, JavaScript fetching Endpoint

Hi, my method getSeconds() is not invoked.

@PostMapping("/get-seconds")
    public ResponseEntity<Integer> getSeconds(@RequestBody ModulUpdateRequest request) {
        log.info("called get-seconds");
        return ResponseEntity.ok(modulService.getSecondsForId(UUID.fromString(request.fachId())));
}

this is my fetch:

export async function getSeconds(fachId) {
    try {
        const csrfToken = getCsrfToken();
        console.log("csrf=" + csrfToken)

        const response = await fetch('/api/get-seconds', {
            method: 'POST',
            credentials: "include",
            headers: {
                'Content-Type': 'application/json',
                'X-XSRF-TOKEN': csrfToken
            },
            body: JSON.stringify({ fachId })
        });

        console.log(response)


        //if (!response.ok) {
        //    throw new Error(

HTTP error! Status: ${response.status}

);
        //}
        return await response.text();

    } catch (error) {
        //console.error('Fehler beim Abrufen der Sekunden:', error);
    }
}
