Branch matrix shorten Url not fetch og:url facebook share debug

Question

I have recently build an application and I am using branch IO for sharing and tracking the users activities for product share and user's event track. The basic config I have done to create the branch universal object as:

Code Sample:

let branchConfig = {
    canonicalIdentifier: product/details/12345, 
    canonicalUrl : "https://example.com/product/details/12345",
    title : "Some title text ",
    contentDescription : "desc of product",
    contentImageUrl : "https://example.com/product.product/image/12345",  
    contentIndexingMode: 'private',
    contentMetadata : {
        createdBy : "user_id", 
        creation_time : Date.now(),
        deeplinkType  : "Custom data"
    }
};
Branch.createBranchUniversalObject(branchConfig)
.then((initbranch) => {
    analytics = { 
        channel  : "Unknown",
        feature  : "sharing",
        campaign : "Marketing",
        stage    : '',
        tags     : ['some text and more'],
        type     : 2
    };
    let properties = {
        $fallback_url: "https://example.com/product/details/12345",
        $desktop_url: "https://example.com/product/details/12345",
        $android_url: android_play_store_url, 
        $ios_url: ios_app_store_url, 
        $ipad_url : ios_app_store_url,
        $og_image_url: "https://example.com/product.product/image/12345",
        $og_title : "Some title text ",
        $og_description : "desc of product",
        $always_deeplink: true,
        $deeplink_path: "product/details/12345"
        $ios_passive_deepview : "default_template",
        $android_passive_deepview : "default_template",
        $match_duration: 7200,
        $canonical_url : "https://example.com/product/details/12345",
        $og_url : "https://example.com/product/details/12345",
        $uri_redirect_mode : 1
    };
    return initbranch.generateShortUrl(analyticsOptions, properties);
})
.then((result) => {
    Promise.resolve(result.url);
})
.catch((err) => {
    console.log(err);
});

The above code returns me a shorten url to share. But when I debug the url with facebook sharing debug, it tells og:url is not found. But on webpage the og:title, og:image, og:description, og:url all are mentioned. Other meta tags like image, title,description are being fetched but og:url is missing.

Please help why facebook sharing debug is not getting og:url. Because of this the url is getting blocked by facebook or marked as spam. Or if i am missing some thing please guide me to get the actual context.

Thank You :)

Answer 1

I fixed this issue by modifying some context. If we use $fallback_url, the facebook crawel fetch details from the fallback_url which holds a branch session Id.

And the url mismatch in this scenario. As I am defining all respective url types like desktop, ios, android, etc so no need of fallback Url. I commented out the section

$fallback_url: "https://example.com/product/details/12345"

It worked.

I debugged the shorten url on https://developers.facebook.com/tools/debug/og/object/ and https://developers.facebook.com/tools/debug/sharing.

Both returned me the true data.
