As per the CanFulfillIntentRequest documentation:
"Default values using the entity resolution implementation from the Alexa Skills Kit
The Alexa Skills Kit provides entity resolution. If your skill uses the entity resolution data to understand slot values, the default value for
canUnderstand is as follows.
canUnderstand= "YES" if entity resolution successfully resolves slot value.
canUnderstand= "NO" if entity resolution does not resolve slot value.
If you want, you can overwrite the default."
I am wondering what does the default mean here? How can we know which slot is set by default without getting the entity resolution from the request? Does it mean that if we didn't return the canUnderstand value for the slot, the slot will be set by default if we used entity resolution?
Thank you very much for the help.
