Firebase Async/Await DeprecationWarning: Unhandled promise rejections are deprecated - firebase

Question

I am trying to create a simple connection to my Firebase Realtime-Database using Functions with Async/Await to reduce code and even thou I wrap the code using try/catch, it still throws the following error.
exports.createBlogPost = functions.https.onRequest(async (req, res) => {
try {
cors(req, res, () => { });
const response = req.body;
response.createDate = new Date();
const snapshot = await admin.database().ref(BLOG_POSTS).push(response);
console.log("SNAP", snapshot.getKey());
response.id = snapshot.getKey();
res.send(response);
} catch (e) {
res.status(500).send(e);
}
});
It creates the instance in the database but I receive the following warning:
info: SNAP -LdnpewpwEz9EOkAA05H
