jsfiddle with knockout getting errors

I can't figure out what the error in the console means when I run my jsfiddle.

Fiddle here

And this is the beginning of the error:

    jQuery.Deferred exception: Unable to process binding "foreach: function (){return items }" Message: Unable to process binding "value: function (){return itemNo }" Message: itemNo is not defined

anonymous/<.value@https://cdnjs.cloudflare.com/ajax/libs/knockout/3.4.1/knockout-min.js line 68 > Function:1:58 a.d.value.init/m@https://cdnjs.cloudflare.com/ajax/libs/knockout/3.4.1/knockout-min.js:102:301 z.Qc@https://cdnjs.cloudflare.com/ajax/libs/knockout/3.4.1/knockout-min.js:51:391

That is all in yellow but there is a single red error at the bottom: ReferenceError: itemNo is not defined. It bugs me that the console never gives relevant line numbers. I supposed with libraries, partial views, layouts, etc, it makes it difficult.

The error is saying that itemNo dose not exist in your foreach context and that's because you are passing the entire array of json as string so you need to parse your json string.

Try : ko.mapping.fromJS(JSON.parse(items),{},self.items).
