Fatal error when Woocommerce custom field is triggered

问题

I have a custom field for woocommerce products. This field outputs an image in woocommerce emails. However, since I'm using Woocommerce Bookings (custom product type) plugin as well, upon confirmation of the booking, my site crashes down. This is the code that output custom field:

//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
        }
    }
}

This is the error that I'm getting in the logs:
