Open Graph Plugin 2.0.2 CustomTag adding problem

Open Graph Plugin 2.0.2 CustomTag adding problem

Hello
The following example is valid for generating links related to open graph and most plugins generate links in this way.

<meta property="og:title" content="How to Become an SEO Expert (8 Steps)" />
<meta property="og:description" content="Get from SEO newbie to SEO pro in 8 simple steps." />
<meta property="og:image" content="https://ahrefs.com/blog/wp-content/uploads/2019/12/fb-how-to-become-an-seo-expert.png" />

but I installed the joomshopping plugin, it produces links as follows

<meta property="og:title" content="How to Become an SEO Expert (8 Steps)">
<meta property="og:description" content="Get from SEO newbie to SEO pro in 8 simple steps.">
<meta property="og:image" content="https://ahrefs.com/blog/wp-content/uploads/2019/12/fb-how-to-become-an-seo-expert.png /">

it doesn't add the content end " />
For example, the end of the url ends like this /" >
content ends like this " >

i think there seems to be a problem adding CustomTag i am using latest version Open graph 2.0.2

//product
function onBeforeDisplayProductView(&$view) {
$link = \JURI::getInstance();
$lang = \JSFactory::getLang();
$doc = \JFactory::getDocument();
$jshopConfig = \JFactory::getConfig();

$locale = $lang->lang;
$type = 'product';
$url = $link->getScheme() ."://" . $link->getHost() . $link->getPath()."/". $link->getQuery();
$image = $link->getScheme() ."://" . $link->getHost()."/components/com_jshopping/files/img_products/".$view->product->image;
$site_name = $jshopConfig->get( 'sitename' );

$doc->addCustomTag( '<meta property="og:locale" content="'.$locale.'" />' );
$doc->addCustomTag( '<meta property="og:title" content="'.$view->product->name.'" />' );
$doc->addCustomTag( '<meta property="og:type" content="'.$type.'" />' );
$doc->addCustomTag( '<meta property="og:url" content="'.$url.'"/>' );
$doc->addCustomTag( '<meta property="og:image" content="'.$image.'" />' );
$doc->addCustomTag( '<meta property="og:site_name" content="'.$site_name.'" />' );
}
