arangojs collections() errors return

Question

I'm totally green with it all. Sorry, but I cant get this thing to work at all node.js + arangojs >

const myColl = async () => {//new Promise((resolve, reject) => {
    try {
        const db = await new Database({
            url: "http://localhost:8529",
            databaseName: "testDB",
            auth: {username: "userTest", password: "userTest"},
        });
        console.log(db)
        try {
            let collection = await db.collections();
            console.log(collection);
        } catch (err) {
            console.log(err);
        }
    } catch (err) {
        console.log("Failed to login db ", err)
        return
    }
}
myColl()

I just end up with :

Database {_analyzers: Map(0), _collections: Map(0), _graphs: Map(0), _views: Map(0), _connection: Connection, ...}
