In the first post, the address slot type (AMAZON.PostalAddress) was shown in the Alexa Simulator as being populated with 5750 claude drive as a valid address entry to be sent to the Skill. This indicates the Simulator had a small bug in it that has since been corrected by Amazon. For all other numeric data slots, the numbers have to be spelled out with words.
For example, zip codes have to be entered as seven five zero zero one instead of 75001.
The house number should have been required to be spelled out as five seven five zero instead of 5750.
New Method in Address Slot (corrected)
Old Method (with bug)
