Menu
I have created a simple Node.js web server to render html content on the browser. Specifically the html contains meta tags for sharing on social media to enable URL preview as soon as the website link is shared on social platforms like FB,Twitter,LinkedIn,etc.
I have already added open graph tags for sharing in the returned html content. It works well for FB and Twitter but gives an error with "We encountered a server error while trying to inspect the URL." as response.
Here is code of server with a dummy endpoint.
const express=require('express');
const app = express();
require('dotenv').config();
app.get('/dummy',(req,res)=>{
res.send(`
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Dummy Endpoint</title>
<meta name="type" content="article" />

})
app.listen(process.env.PORT || 5000, () => {
console.log('Server started at '+process.env.PORT)
});
Website link : https://whispering-woodland-66525.herokuapp.com/dummy (Page is empty, check head section in Inspect)
Response of Facebook sharing debugger : https://developers.facebook.com/tools/debug/?q=http%3A%2F%2Fwhispering-woodland-66525.herokuapp.com%2Fdummy
Response of LinkedIn Post Inspector : https://www.linkedin.com/post-inspector/inspect/https:%2F%2Fwhispering-woodland-66525.herokuapp.com%2Fdummy
I have tried out refreshing the Post Inspector page multiple time and adding a dummy query parameter to the the url in the Post Inspector to prevent serving of cached content, but things are not working out.
I am unable to understand if there is something wrong or missing in the code or is it a problem with LinkedIn web crawlers.

I believe LinkedIn Post Inspector is expecting a complete HTML document. Consider wrapping your metadata into the header of the document. Try returning:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Dummy Endpoint</title>
<meta name="type" content="article" />
<meta name="title" content="Dummy Endpoint"/>
<meta name="description" content="Used for testing"/>
