ERROR SHORTCODE

Hello,

I am using shortcode, as indicated in the documentation [wcb_widget always_visible=1 show_coupon_code=1].

However when I click on the submit button, it throws a javascript error, and the form is not submitted.

The error is this: wcb_params is not defined

The error is in the woocommerce-coupon-box/js/shortcode-script.js file.

I attach a screenshot with the error.

You can fix it?

Thank you
