What?
Not sure what this is but it's an article listing some errors in Zoho Books when using the shortcode command to retrieve the details for an item in Zoho Books...

Why?
I have no idea. I cannot for the life of me figure out why this item does not appear. I can see it in the list view using the interface. When i just do the commaind 
info item
it shows me the record; but if I use zoho.books.getRecordsByID() other than being grammatically incorrect, it does not work... I think it's the product/item record.

How?
I tried various ones including an invokeUrl and then a colleague gave me the following. I hope it helps someone else out there too...
Note that connection zbooks has zohobooks.fullaccess.all and this code is on the EU datacenter: 

info item;
// yields {the correct record}

info zoho.books.getRecordsByID("item","12345678901","123456000000987654","ab_books");
// yields Exception : Invalid JSON Format String

r_Item = invokeurl
[
	url: "https://www.zohoapis.eu/books/v3/items/"+item.get("item_id")+"?organization_id="+organization.get("organization_id")
	type: GET
	connection: "ab_books"
	detailed: true
];
info "This Item: " + r_Item.toString();
// yields This Item: 
// "responseCode":500

info zoho.books.getRecordsByID("elephants","12345678901",123456000000987654,"zbooks");
