Okta Angular, error 500

hi, I have a hard time passing the right angular request to the header. This is my service:

import { Injectable } from '@angular/core';
import { HttpClient, HttpEvent, HttpHandler, HttpInterceptor, HttpRequest, HttpHeaders } 
from '@angular/common/http';
import { Utente } from '../model/Utente ';
import { Prodotto } from '../model/Prodotto ';
import { OktaAuthService } from '@okta/okta-angular';
import { Observable, from } from 'rxjs';
import { Carrello } from '../model/Carrello ';
import { userInfo } from 'node:os';
import { getLocaleCurrencyCode } from '@angular/common';

const headers = new HttpHeaders().set('Accept', 'application/json');

 providedIn: 'root'
export class HttpClientService {

private httpClient:HttpClient, private oktaAuth:OktaAuthService     ) {}

return this.httpClient.get<Carrello[]>('http://localhost:8080/prodotti/utente/vedicarrelloo', {headers} );


This is my spring method:

@Transactional(readOnly = true)
public List<Carrello> getCarrello(@AuthenticationPrincipal OidcUser utente){
    Utente u= utenteRepository.findByEmail(utente.getEmail());
    return carrelloRepository.findByUtente(u);

In console I get this error:


this error corresponds in my console to "java.lang.NullPointerException: null.

But if I access localhost: 8080, I can see the answer correctly, so I assume there is a problem in passing the request header in angular, can anyone tell me where am I wrong, please? I specify that I get this error only in the methods where the OidcUser is present, the rest works perfectly. Thank you!


It looks like OidcUser object is null ? Not sure if this is related to the headers as you’ve mentioned.

What could it be? if I access from the client, then from localhost: 8080, I see the requested info and then the oidcUser object
