findItemsByProduct: Unexpected character '@' (code 64) in content after

[eswarreddy43]

Hello Dev,

I am using this nodejs-ebay-api module for searching the book using ISBN in app. So I took reference of this findItemsByProduct from eBay developers site. I have tried my code like following

var parameters = {
    productId:{ '__value__': "9788172234980", '@type': 'ISBN' },
    outputSelector: ['AspectHistogram'],
    paginationInput: {
        entriesPerPage: 10
    }
};
ebay.xmlRequest({
    serviceName: 'Finding',
    opType: 'findItemsByProduct',
    appId: 'My-app-id',
    params: parameters
}, function itemsCallback(error, itemsResponse) {
    if (error) throw error;
    var items = itemsResponse.searchResult.item;
    console.log('Found', items.length, 'items');
    //console.log(items[0].sellingStatus.currentPrice.amount);
    for (var i = 0; i < items.length; i++) {
        console.log(items[i].title);
    }
});

But getting error as

EbayClientError: Bad response status code 500 <?xml version='1.0' encoding='UTF-8'?><errorMessage xmlns="http://www.ebay.com/marketplace/search/v1/services"><error><errorId>5014</errorId><domain>CoreRuntime</domain><severity>Error</severity><category>System</category><message>Error reading from XML stream: Unexpected character '@' (code 64) in content after '&lt;' (malformed start element?).

Please suggest me on this.

If this is still relevant, or interests anyone.

To add the attribute <productId type="ReferenceID">53039031</productId>
with the xml module which ebay-api use, you should take a different approach while building the xml.

It's easy to add.
You can edit buildXmlInput(options) function in xml-request.js.
if (options.serviceName === 'Finding') { root.push({'_attr': {'xmlns': 'http://www.ebay.com/marketplace/search/v1/services'}}); /////////////////Added code to support find items by product/////////////////////////////// if(options.opType=== 'findItemsByProduct'){ root.push({'productId': [{ '_attr': { 'type': 'ReferenceID'}}, options.productId]}); } ////////////////////End added code//////////////////////////////////////// }

You should also add a productId field in the options Object of course.
