Java Conflict b/w WPUserFrontend & Woocommerce

I got the following error on my console.

I think this is the conflict between WP User Frontend and WooCommerce. ( I found uniqueId defined as somethink in woocommerce flexslider js file.)

Is there any way to fix it? (This error appears only on this form. My other form: https://www.tradybees.com/blood-donar-registration/)

I want to use both of the plugins.

Also, check from SOURCE->SITE->WP-CONTENT->PLUGINS to check which is causing this.
