400 Bad Request: "Value cannot be null. (Parameter source)" when updating BaseItemDto

[JanBi 0]

I am trying to update Items of my library via emby rest api in Java

What is working?

Getting a BaseItemDto via "localhost:8096/Users/376be745cbec4706a5282b916f15627d/Items/338"

final BaseItemDto response3 = restClient.get()
                .uri(uriBuilder -> uriBuilder
                        .path("/Users/376be745cbec4706a5282b916f15627d/Items/338")
                        .build())
                .retrieve()
                .body(BaseItemDto.class);
        logger.info("Response3: {} | {} | {} | {} | {}", response3.getName(), response3.getPath(), response3.getListingsPath(), response3.getId(), response3.getGuid());

What is not working?

Updating an attribute of BaseItemDto

response3.setName("new_name");

final ResponseEntity<Void> response4 = restClient.post()
  .uri(uriBuilder -> uriBuilder
  .path("/Items/338")
  .build())
  .contentType(MediaType.APPLICATION_JSON)
  .body(response3)
  .retrieve()
  .toBodilessEntity();

What is the Exception on the client side?

Thank you in advance for any advice

Forget to mention my Header:

var factory = new HttpComponentsClientHttpRequestFactory();
        factory.setConnectTimeout(10000);
        factory.setReadTimeout(10000);

final RestClient restClient = RestClient.builder()
        .requestFactory(factory)
        .baseUrl("http://localhost:8096")
        .defaultHeader("X-Emby-Token", "b14a2b8489324b9ba19a7e00d2de9b36")
        .defaultHeader("Authorization", "Emby")
        .defaultHeader("UserId", "376be745cbec4706a5282b916f15627d")
        .defaultHeader("Client", "Emby Classic")
        .defaultHeader("Device", "Windows Notebook")
        .defaultHeader("DeviceId", "cxyz")
        .defaultHeader("Version", "1.0.0.0")
        .build();

Most likely this is because of a missing ProviderIds field in the BaseItemDto JSON.

You can try adding 

"ProviderIds":  {},

to the JSON. Or change the item via UI so that it gets a providerid.

I'm not sure why the Emby SDK RestAPI: getUsersByUseridItemsById API doesn't return it (even when empty). @Luke ?
