I have a custom slot with a few reference values. It is important that values not on the Custom Slot Values list are still issued in the Alexa JSON output to Lambda.
Per Amazon doc this should be OK: "Note that a custom slot type is not the equivalent of an enumeration. Values outside the list are still returned if recognized by the spoken language understanding system."
This all worked fine until today.
With no changes to the interaction model, it has now stopped working.
The slot now has no value for any slot value not on the Custom Slot Values list.
Anyone know what has happened?
