触发Woocommerce自定义字段时出现致命错误

Question

我对woocommerce产品有一个自定义字段。此字段在woocommerce电子邮件中输出图像。但是，由于我也使用了Woocommerce Bookings（自定义产品类型）插件，因此在确认预订后，我的网站崩溃了。这是输出自定义字段的代码：

//adds image to header
add_action('woocommerce_email_header', 'wcv_ingredients_email_logo', 10, 2);
function wcv_ingredients_email_logo( $email_heading, $email ){
    if($email->object){
        foreach($email->object->get_items() as $item_values){
            // Get the product ID for simple products (not variable ones)
            $product        = $item_values->get_product();
            $image_id       = get_post_meta( $product->get_id(), 'store_logo_email', true ); //get the image ID associated to the product
            $image_src      = wp_get_attachment_image_src( $image_id, 'medium' )[0]; //get the src of the image - you can use 'full', 'large', 'medium', or 'thumbnail' here,
            $image          = '<div align="center"><img src="'.$image_src.'"></div>'; //create the img element
            echo $image . '<br>'; //echo the image
        }
    }
}

这是我在日志中遇到的错误：
