Spring Boot DTO values are recevied null

I send this data from Front with headers {'Accept': 'application/json', 'Content-Type': 'application/json'}

{
    "libelle": "Article AB",
    "dimension": {
        "id": 0,
        "code": "BIJOUTERIE",
        "label": "Bijouterie"
    },
    "categorie": {
        "id": 1,
        "code": "FEMMES",
        "label": "Femmes"
    },
    "famille": {
        "id": 0,
        "code": "BELDI",
        "label": "Beldi"
    },
    "type": {
        "id": 2,
        "code": "MDEMA",
        "label": "Mdema"
    },
    "picture": "text",
    "description": null,
    "prixVente": 5000,
    "poids": null,
    "status": null,
    "enabled": true,
    "barcode": "4351951317874",
    "annee": null,
    "boitier": null,
    "mouvement": null,
    "taille": null,
    "diametre": null
}

I receive it like this, only one value and others are null, nest values are null

libelle=Article AB,
description=null,
dimension=null,
enabled=true,
categorie=null,
famille=null,
type=null,
picture=null,
prixVente=0.0,
poids=0.0,
status=null,
barcode=null,
annee=0,
boitier=null,
mouvement=null,
taille=0,
diametre=0.0

this is my post function in front

 post(url: string, body: any, options?: any): Observable<any> {
        return this.http.post<any>(url, JSON.stringify(body), newHeaders(options));
    }

this is my Rest controller

import org.springframework.web.bind.annotation.ResponseBody;
    @RequestMapping(value = "/article", method = RequestMethod.POST)
    @PreAuthorize("hasRole('ROLE_CREATE_ARTICLE')")
    public ResponseEntity<Long> addArticle(@RequestBody ArticleDto article) throws Exception {
        
        article = articleService.createArticle(article);
        
        return new ResponseEntity<Long>(article.getId(), HttpStatus.CREATED);

    }

I tried to add @JsonProperty, @Builder but same problem

EDIT : using Objectmapper I'm getting this error:
