Issue

This Content is from Stack Overflow. Question asked by ivan rodriguez

good day, some time ago I bought a custom plugin and I am having the following error, I tried to contact the developer but it was not possible, I am not a programmer so within my little knowledge I cannot appreciate where the problem is, I would greatly appreciate it if you could help assess what should be corrected.

CRITICAL Uncaught Error: Call to a member function get_price() on null in /home/runcloud/webapps/DoggysMarket/wp-content/plugins/wayra-discount-surcharge/public/class-wayra-discount-surcharge-public.php:158

I did the check of the fragment but I can’t see what the error is, in my opinion everything is fine but as I said, I’m not a programmer and I don’t know if any function or fragment is wrong, line 158 of the error is this: $product_price = $product->get_price(); and the code snippet is as follows

// Show second price on Store and related products
        $show_on_store = $this->config['show_on_store'] ?? false;
        if ( ( ( is_product() && $wp->query_vars['product'] == $product->get_slug() )||$show_on_store ) && isset( WC()->session ) && 'no' != $show_discount_or_surcharge && 'no' != $show_discount_or_surcharge_cat ) { 
            
            $display_tax_mode = get_option( 'woocommerce_tax_display_shop' ); // incl = show tax on product price on product page

            $product_price = $product->get_price();
            if ( wc_tax_enabled() ) {
                if ( ! wc_prices_include_tax() && 'incl' == $display_tax_mode ) {
                    $product_price = wc_get_price_including_tax( $product );
                } elseif ( wc_prices_include_tax() && 'excl' == $display_tax_mode ) {
                    $product_price = wc_get_price_excluding_tax( $product );
                }
            }
            
            $difference = $this->wayra_wds_get_difference( $product_price );
            $fixed_price = $product_price + $difference;

            $price .= '<div class="wds">';
            
            if ( ! empty( $this->config['text_after_price'] ) ) {
                $price .= '<div class="wds-text first">' . $this->config['text_after_price'] . '</div>';
            }

            
                
            if ( $product->is_type( 'variable' ) ) {

I appreciate if you can give me an orientation of the step to follow to solve my problem, thank you very much
