FbaOutboundApi : ERROR Use CreateFulfillmentOrderRequest()

[DIGIWEBFR]

Hi,
I have a problem while using the API: CreateFulfillmentOrderRequest.

Example :

    $AddressObj = new Address();
    $AddressObj->setName('TITI');
    $AddressObj->setAddressLine1('Strettetet WWW');
    $AddressObj->setCity('GGG TTUTU');
    $AddressObj->setPostalCode('75000');
    $AddressObj->setStateOrRegion('PARIS');
    $AddressObj->setDistrictOrCounty('PARIS');
    $AddressObj->setCountryCode('FR');

    $oElt = new CreateFulfillmentOrderItem();
    $oElt->setSellerSku('20114456456');
    $oElt->setQuantity(1);
    $oElt->setSellerFulfillmentOrderItemId('20114456456-1');

    $CreateFulfillmentOrderRequest = new CreateFulfillmentOrderRequest();
    $CreateFulfillmentOrderRequest->setSellerFulfillmentOrderId('CDC0155416516465');
    $CreateFulfillmentOrderRequest->setDisplayableOrderId('CDC0155416516465');
    $CreateFulfillmentOrderRequest->setDisplayableOrderComment('Orders F');
    $CreateFulfillmentOrderRequest->setDisplayableOrderDate('2022-01-12T12:46:45.809Z');
    $CreateFulfillmentOrderRequest->setDestinationAddress($AddressObj);
    $CreateFulfillmentOrderRequest->setItems([$oElt]);

    $CreateFulfillmentOrderRequest->setShippingSpeedCategory('Standard');
    $CreateFulfillmentOrderRequest->setMarketplaceId('sdfqjsdnfjkqnsd);

    $apiInstance = $this->amazonInstanceApi();
    $createFulfillmentOrder = $apiInstance->createFulfillmentOrder($CreateFulfillmentOrderRequest);
