XML as JSON attributes in GetLowestPricedOffersForSKU response

[dbruce1990]

I am trying to pull data from the GetLowestPricedOffersForSKU products api call, but I appear to be getting XML as JSON attributes in the response. Here the first few lines of the response I am getting: {"data":[{"<?xml version=\"1.0\"?><GetLowestPricedOffersForSKUResponse xmlns=\"http://mws.amazonservices.com/schema/Products/2011-10-01\">":" <GetLowestPricedOffersForSKUResult MarketplaceID=\"ATVPDKIKX0DER\" SKU=\"20180219_StVincentDePaul@Seneca_16\" ItemCondition=\"Used\" status=\"Success\">"},{"<?xml version=\"1.0\"?><GetLowestPricedOffersForSKUResponse xmlns=\"http://mws.amazonservices.com/schema/Products/2011-10-01\">":" <Identifier>"},{"<?xml version=\"1.0\"?><GetLowestPricedOffersForSKUResponse xmlns=\"http://mws.amazonservices.com/schema/Products/2011-10-01\">":" <MarketplaceId>ATVPDKIKX0DER</MarketplaceId>"},{"<?xml version=\"1.0\"?><GetLowestPricedOffersForSKUResponse xmlns=\"http://mws.amazonservices.com/schema/Products/2011-10-01\">":" <SellerSKU>20180219_StVincentDePaul@Seneca_16</SellerSKU>"},{"<?xml version=\"1.0\"?><GetLowestPricedOffersForSKUResponse xmlns=\"http://mws.amazonservices.com/schema/Products/2011-10-01\">":" <ItemCondition>Used</ItemCondition>"},{"<?xml version=\"1.0\"?><GetLowestPricedOffersForSKUResponse xmlns=\"http://mws.amazonservices.com/schema/Products/2011-10-01\">":" <TimeOfOfferChange>2018-07-13T22:18:20.937Z</TimeOfOfferChange>"},{"<?xml version=\"1.0\"?><GetLowestPricedOffersForSKUResponse xmlns=\"http://mws.amazonservices.com/schema/Products/2011-10-01\">":" </Identifier>"}...

API Call :

amazonMws.products.search({
        'Version': '2011-10-01',
        'Action': 'GetMatchingProduct',
        'SellerId': '***********',

        'MarketplaceId': '****',

        if (error) {
            console.log('error products', error);
            return;
        }
        console.log('response ', JSON.stringify(response));
        // console.log('response ', response);
    });

I just realized you are testing GetMatchingProduct, I am trying to call Amazon's GetLowestPricedOffersForSKU. I am not manipulating the response object at all, I am currently just printing out what your library is returning and still getting XML as JSON objects.

[bhushankummar]

@dbruce1990 Okay. I will check again. Also, please send me your API call. So, I can confirm same on my end.

[dbruce1990]

let options = {
    Version: VERSION,
    Action: 'GetLowestPricedOffersForSKU',
    MarketplaceId: MARKET_PLACE_ID,
    SellerId: SELLER_ID,
    SellerSKU: sku,
    ItemCondition: 'Used',
}

amazonMws.products.search(options).then(res => console.log(res)).catch(err => console.log(err))

It seems like treating it as CSV/tabdelimited text.

[bhushankummar]

Current GetLowestPricedOffersForSKU done using GET request.

Expected GetLowestPricedOffersForSKU should done using POST request.

[marcospampi]

I tried it with the latest development version and __RAW__, I got another 'error' though, but other product's APIs works, apart from GetLowestPricedOffers(SKU & ASIN)

{
    "Headers": {
        "x-mws-quota-max": "200.0",
        "x-mws-quota-remaining": "194.0",
        "x-mws-quota-resetson": "2018-07-22T21:26:00.000Z",
        "x-mws-timestamp": "2018-07-22T21:02:31.333Z",
        "content-type": "text/html",
        "content-charset": "unknown",
        "content-length": "86",
        "date": "Sun, 22 Jul 2018 21:02:31 GMT"
    },
    "data": "Failed processing arguments of org.jboss.resteasy.spi.metadata.ResourceMethod@28b9d9b5"
}

Looks like an amazon issue in my case.

@dbruce1990 I have made a fix for this. However, still, I am testing it and release it with a new version shortly.
