"getInputType error: Unable to determine input type for object" when opening config form
When I open settings for this plugin in Homebridge UI, I see this in the JS console (twice for each):

```
getInputType error: Unable to determine input type for object
schema – {title: "params", type: "object"}
```

I noticed this because whenever I try to select text or move a slider, the whole interface crashes. The Safari tab then becomes unresponsive and right click doesn't work It requires a page refresh to work again. Sorry if this has been reported before but I couldn't find anything related in previous issues.

I'm running the latest version of Homebridge (and your plugin) on a Pi Zero. Bug noticed in Safari (v13.1.1). The errors also appear in Chrome but the interface does not crash, it just behaves a little... odd.

Happy to provide anything you might need to figure this out but I suspect you'll see the same errors as I do since it happened right from fresh install (hadn't even filled out the initial config form yet).
