Webmaster tool validation for JSON + ld structured data

Question

I am using Structured Data Markup for a product page. And using json + ld and have put the script tags in the header section.

The script section is marked by two lines. And when I validate the JSON segment in http://json-ld.org/playground/index.html it gives a proper output. But when I validate it with Google webmaster tools it does not show me the content. http://www.google.com/webmasters/tools/richsnippets

Kindly help me in identifying any issue with this. I think I have made this correctly.

For More Info , I am posting the JSON segment with this.

<script type="application/ld+json"> {
"@context": "http://schema.org",
"@type": "Product",
"productID": "mpn:20AV002YMB",
"description": "Whether you re an overachiever or an up-and-comer, ThinkPad laptops are the tools you need.

Google Webmaster Tools does not support JSON-LD (at time of writing) However Google Search does.

You can see this thread for more information:

and use Google's beta markup tester for email:

https://www.google.com/webmasters/markup-tester/ (which will also work for web HTML) - Your JSON validates here

I know this is an old thread, but I thought it might be useful for anyone searching for answers to this who lands here.
