In the NFI word doc, in the "Testing Name Free Interaction In Isolation" section, it mentions that you should have at least 10 utterances for your intent. But when I add more than 5 the build fails in the Alexa Developer console with the message "Ingress point can only include up to five sample utterances."
To be clear, I adding the extra utterances in the _nameFreeInteraction -> ingressPoints -> type=INTENT -> sampleUtterances section of my json and saving building through the Alexa Developer web console
Thanks!
