Working in this trailhead and have everything configured by when I "ask deploy" in step 3, I get the following:

-------------------- Create Skill Project --------------------

Skill Id: amzn1.ask.skill.396c51be-4f7c-437e-907d-70fb0301add8
Skill deployment finished.
Model deployment finished.
Create role error.

I just cannot see the error. What am I missing?

Hi,

Problem saving MyContactList.cmp.

public static List<Contact> getContacts(Id recordId) {
   return [Select Id, FirstName, LastName, Email, Phone From Contact Where AccountId = :recordId];
}
}
