When I execute the route "/ new-article" the article is added to the database, but the server does not send a reply to the client. I noticed that this stems from the fact that the constant ris has no insertedCount property and this causes the if condition to never be true, preventing you from executing res.send ()

app.get('/new-article', async (req, res) => {
    const articolo = {
        titolo: 'Titolo articolo 1',
        testo: 'Testo articolo 1',
        autore: 'Leonardo',
        tag: ['node.js', 'javascript', 'mongoDB']
    }
    const ris = await articoliCollection.insertOne(articolo);

    if(ris.insertedCount === 1) {
        res.send('Nuovo articolo inserito correttamente')
    }
});
