Error: process is not defined

I was using version 8.1.0 with no issues. I updated this morning to version 8.1.5 and I started getting this error:
`Error: process is not defined`

It occurs when I call a feed's `get()` method.

```
const client = StreamConnect(API_KEY, accessToken, APP_ID);
const feed = client.feed('feedname', userId);
feed.get({ limit: 0 })
```
