500 Error when navigating to https://graph.api.smartthings.com/device/list.
Steps completed to date:
Removed all Device Handlers
Removed all SmartApps
Removed the last 2 pieces of hardware that were being implemented when error started.
error still persists
what happens if you click on My Locations: devices?
It takes me to a list of devices. not the 500 error page.
probably a good time to contact ST support and let them troubleshoot from their end https://support.smartthings.com/hc/en-us
Are you on the right shard? Best practice is to login through account.smartthings.com so it automatically directs you to the right shard.
