Unable to fetch smartthings devices to Homebridge
I have installed Homebridge on my Rpi and followed all instructions. I also have JSON API version 0.5.5 on my iphone, yet I can't seem to fetch any smartthings devices.  I have updated/published the API, Homekit detects homebridge but it's grayed out due to no devices listed. Your help would be appreciated, I'm first time user and learning pretty quickly, but stuck on this. See my config.json and also the errors message:
