I've nearly finished my lambda service(adapter) for my smart home skill to operate a thermostat.
The Echo dot is receiving my request and relaying their information in case of success criteria meet.
In case of validation/error i am not getting the actual message sent with context.fail, it is saying something generic like:'thermostat not responding'
how we could send the validation/error message whatever we fill in ex: 'Heat temperature could not be grater than 95'. and same should be replied by echo dot device.
