Keep getting `Error 422` upon setting switch state
**Describe the bug**
For some unknown for me reason, I'm keeping to receive `Error 422` sending POST request to SmartThings API to start my vacuum cleaner. I tried the same request in Postman and it works as expected. But once I put the request into plugin config I get ```Error occurred setting state of switch: HTTP request returned with error code 422``` upon triggering the switch


**Version** (output of `npm list -g homebridge homebridge-http-switch`)
 - homebridge: `1.6.0`
 - homebridge-http-switch: `0.5.36`
