Hi Team,

The client dgraph-js-http breaks when setting the Slash API key.

See [dgraph-js-http/clientStub.js at master · dgraph-io/dgraph-js-http · GitHub](https://github.com/dgraph-io/dgraph-js-http/blob/master/lib/clientStub.js#L274-L280)

`setSlashApiKey(apiKey)` is missing the following to create headers if undefined.

```auto
this.options.headers === undefined && (this.options.headers = {});

```

Hence, one would get a `TypeError: this.options.headers is undefined`

I have submitted a PR [Fix issue where setSlashApiKey would break if no headers was set. by Sydney-o9 · Pull Request #34 · dgraph-io/dgraph-js-http · GitHub](https://github.com/dgraph-io/dgraph-js-http/pull/34)
