Duvida Springboot + RestFul

Pessoal, estou tendo um problema com minhas solicitações Rest.

Até um tempo atras meu código estava funcionando normalmente, porem, um a duas semanas atras, minhas requisições param de funcionar, exceto os métodos GET e Delete

GET 
@RequestMapping(value = "/api/estabelecimentos", method = RequestMethod.GET, produces = "application/json")
    	public @ResponseBody List<Estabelecimento> getAllEst() {
    		return er.findAll();
    	}

Delete
    @RequestMapping(method = RequestMethod.DELETE, value = "/api/estabelecimentos/{id}", produces = "application/json")
    	public ResponseEntity<Estabelecimento> deleteEst(@PathVariable Long id) {
    		er.deleteById(id);
    		return new ResponseEntity<Estabelecimento>(HttpStatus.OK);
    	}

Os demais métodos (POST e PUT) me retornam erro 415 via client (Postman) e no log do springboot recebo esse retorno;

POST
@RequestMapping(method = RequestMethod.POST, value = "/api/estabelecimentos", produces = "application/json")
	public ResponseEntity<Estabelecimento> newEstabelecimento(@RequestBody Estabelecimento estabelecimento) {
		er.save(estabelecimento);
		return new ResponseEntity<Estabelecimento>(estabelecimento, HttpStatus.OK);
	}

PUT
@RequestMapping(method = RequestMethod.PUT, value = "/api/estabelecimentos/{id}", produces = "application/json")
	public ResponseEntity<Object> updadeEstabelecimento(@RequestBody Estabelecimento esta, @PathVariable Long id){
		Optional<Estabelecimento> estab = er.findById(id);
		
		if(!estab.isPresent()) 
			return ResponseEntity.notFound().build();
		
		esta.setCod_Estabelecimento(id);
		er.save(esta);
		return ResponseEntity.noContent().build();
	}

Alguém consegue me dar uma luz ? não consegui encontrar nada na internet

Hello Guy, I would like to know if you have found the issue ?

Thx you in advance

Você deve está enviando uma media type diferente no seu cliente http(postman, ajax).

The content-Type is already set on “applicaiotn/json” in the POST/PUT requests headers but the error is linked to the usage of @JsonMAnagedReference / @JsonBackReference annotations is our models to be able to serialize linked objects…

Thank you for your answer if you have any idea on our issue it will be very great for us
