Doesn't want to work?

Hi,

I'm trying to get this working but I get an error:

> TypeError: options.packed is undefined[Learn More]

I've tried it with a selector:

```
const instance = Bricks({
container: "#case-wrapper a"
});
```

and also a direct node for the parent:

```
const instance = Bricks({
container: document.getElementById("case-wrapper")
});
```

What am I doing wrong?

TIA

Andy
