JavaScript error in Chrome – Cannot read properties of undefined

Hello,

I am reporting a JavaScript conflict related to Variation Swatches for WooCommerce (v2.2.3).Environment

• WordPress: 6.9.1
• WooCommerce: 10.5.2
• PHP: 8.3
• Theme: Salient 17.0.6
• Browser affected: Google Chrome (latest version)
• Not reproducible in: Safari / Firefox

Issue Description

When the plugin is active, selecting a product variation on variable products triggers the following JavaScript error in Chrome:

Uncaught TypeError: Cannot read properties of undefined (reading 'template') at wp-util.js at VariationForm.onFoundVariation (add-to-cart-variation.js)

The error occurs during the found_variation event triggered by WooCommerce’s native add-to-cart-variation.js.

As a result:

• The variation price and availability are not properly rendered.
• WooCommerce fails to recognize the selected variation.
• Customers see the message:
  “Please select product options before adding this product to your cart.”
• The product cannot be added to cart.

Important Observation

If the plugin is disabled:

• The error disappears immediately.
• Variation selection works normally.
• Add to cart works correctly in all browsers.

This strongly indicates a JavaScript conflict introduced by the plugin when handling WooCommerce’s variation-template.

It appears that the plugin may be overriding or interfering with WooCommerce’s internal wp.template('variation-template'), which becomes undefined in Chrome and stops script execution.Request

Could you please:

• Confirm compatibility with WooCommerce 10.5.2?
• Verify handling of the found_variation event?
• Check if the plugin correctly loads and preserves WooCommerce’s variation-template?

Let me know if you need additional logs or a staging environment for testing.

Thank you.
