I have built a trivia skill with button support using Echo Buttons Trivia - https://github.com/alexa/skill-sample-nodejs-buttons-trivia. It was working fine when I tested in developer console. However, it was rejected by reviewer with this message. What is the solution?
The skill did not begin with a roll call prompting users to awaken their Echo Buttons. A roll call is required at the beginning of skills utilizing Echo Buttons to ensure the buttons are awake for the remainder of the interaction.
Steps To Reproduce:
User: "Alexa open fruits trivia" Skill: "Welcome to Fruits Trivia. This game supports up to 4 players. How many players are there?" User: "one" Skill: "Fantastic! Are you ready to start the game?"
Please note that the skill must provide roll call in order to awaken the echo buttons before navigating further into the skill.
