Using the ES node library.... how do I do a upsert? After reading documentation, I thought this would work but not having success. My goal is to insert a new document, if it already exists, then update it(or do nothing if there were no changes).

I get `TypeError: Unable to build a path with those params. Supply at least index, type, id`

from:

```
 const upsertArtist = (artist) => {
  var doc = {
    scripted_upsert: true,
    script: {
      index: 'song',
      type: '_doc',
      body: {
        type: 'artist',
        artist: artist
      },
    },

    upsert: {},

  };

  return client.update(doc);
};
```

The content of the `doc.script` needs to go into a nested `body` attribute. Check the [docs](https://www.elastic.co/guide/en/elasticsearch/client/javascript-api/current/api-reference.html#api-update) for the proper syntax.
