Javascript issue "Unexpected token :" : > Error

Like the title says, I have an error of javascript with

`Uncaught SyntaxError: Unexpected token :`

The result of this error is this:

```

```

While I was reading the JSON and validate the JSON between multiple platforms I cannot see the error here...

> Code

The following error is due to this function:

```
jQuery.getJSON('/products/'+getProduct.product_handle+'.js', function(product) {

    product.variants.forEach(function(variant) {
      if (getProduct.sucursal == variant.title){
        jQuery.post('/cart/add.js', {
          quantity: 1,
          id: variant.id
        });
      }
    });

  });
```

> Platforms

I'm working with Shopify with the template language Liquid, inside this liquid I have a `<script>` tag that runs AJAX for calling a method from Shopify.

I know that the error it must have javascript syntax but like I said before I didn't see the error.

**Anyone knows about this error?**

I appreciate every answer.
