JSON empty when is called from another file

I’m learning NodeJS and MongoDB. I dont know what is happening with this function.

getAllUsers = async () = {

let user;
let result = await new Connection().connect();
if (result.status == "ok")
    {
        user = await User.find();

    }
return user;
};

If I make a console.log before return user, it works fine (just print an JSON array with all info of the collection)

The problem is when I call it from another file (in my case, the router). If I do this, I receive an empty json.

Why is this happening?

Thanks for your help!!

>Solution :

When calling your function getAllUsers, you need to add await in front of it since it is an async function.

For example,

var listUsers = await getAllUsers();
