TypeError: null is not an object (evaluating 'Recording.init')

I get the error "TypeError: null is not an object (evaluating 'Recording.init')" during

```
	useEffect(() => {
		Recording.init({
			bufferSize: 4096,
			sampleRate: 44100,
			bitsPerChannel: 16,
			channelsPerFrame: 1,
		});
        })
```

Please help.
