Critical Error when updating variation products

Hi,

I am getting a critical error when trying to update a variation product and when I checked woocommerce > status > logs, it shows the following error:

Uncaught Error: Call to a member function update_meta_data() on bool in /home/1316029.cloudwaysapps.com/exzfjwdfsg/public_html/wp-content/plugins/woocommerce-wholesale-prices/includes/admin-custom-fields/products/class-wwp-admin-custom-fields-variable-product.php:770

Can you please let me know what’s wrong?

The error seems to be related to variable products, which the product I was trying to update is a variable product.

I did not see anything related to variation products in the setup guide though, is assigning wholesale prices to variation products only available for the premium version of the plugin?

Thanks!
