i'm trying out a very simple smart home skill, using steps in https://developer.amazon.com/docs/smarthome/steps-to-build-a-smart-home-skill.html
i'm using login with amazon for oauth. when i tested out the skill, i have no problem with account linking. but when i tried to discover devices, i keep on getting "discovery failed". i don't think my lambda is hit as nothing is logged. and the lambda logs when tested on its own.
thanks in advance for your help.
