I'm trying to create a Amazon Alexa Skills Kit to do some kind of automation which would be required to take speech input comprised of strings and numbers (a-test12fish).
When I've used custom slots in Alexa Skills Kit, it is not letting me key in strings with numbers. When I try to key in ask alexa, dangerZone find a-test12fish, I'm getting the following error:
Error: Invalid text input. Text should begin with alphabets and should only contain alphabets, whitespaces, periods or apostrophes
How can I overcome this error?
