I have created some steps between address and payment form in Magento 2.
When i open the coupon code and want to go on next step ( Payment Page Step ) It gives me an error
Cannot read property 'settings' of undefined in Jquery.validate.js
How to solve this issue actually i want to default open the coupan code but while trying to go on next page it gives me this error.
I will add coupon code ( phtml file ) with this on step three and add coupon code in checkout_index_index.xml.
Any help is appreciated.
