Snipcart Extension Product Crawl Failure

I have been trying to work with the snipcart extension, and I keep running into the same issue on the test check out:

snipcart.js:1 A ‘cart-confirmation’ error occured in Snipcart.

Reason: ‘product-crawling-failed’
*[Details] We have not been able to find item with id ‘5acc1bcf-48ec-4856-9373-07e17e9bdc17’… *

We suggest you take a look at this section of our documentation: http://docs.snipcart.com/configuration/product-definition.

I have checked the product definitions on the checkout button. Wondering if anyone has experience implementing snipcart.
