Bug: failed pushChanges with OpenAPI Connection
### Describe The Bug

Can't access to any SwitchBot Devices (bot, meter, etc.) from homekit

### To Reproduce

I've reset the hub and both Bot from the Switchbot app and reinstalled everything. Then I set the new token in Homebridge. Still errors below. 

### Expected behavior

I should be able to access my switchbot devices
