Clicking on Add to Cart button gives message that goes 'Required Parameter missing or Invalid: Item'

[EatWithBetter]

So this is the page in question, for some reason whenever I click on the Add to Cart button it gives me a message that goes like 'Required Parameter missing or Invalid: Items'. Also attaching a screenshot for reference. FYI the theme I am running my website on is Crave 2.0

Naturally, when I click on the product and then try to ATC, it works just fine, would really appreciate any help on the same.

I can see from the request which is happening in the background that nothing is being sent to Shopify. This is definitely a bug with the theme so you should raise it with the theme developers, their contact information should be located where you installed the theme.
