Mutacja Graphql

Moze ktos bedzie w stanie zobaczyc blad / jak to naprawic. Sam probowalem na kilkanascie sposobow jednak nie wychodzi ;)

mutation  {
  register(userInput:  {    phoneNumber : "222121"  }) {
      userResponse {
        id
      }
  }
}

dostaje cannot query field "UserResponse"on type ErrorOrUserResponse

wiec dla union trzeba napisac ... on
