Null check operator used on a null value and "Bad Element"

I am trying to parse this:

all_shows.graphql

# import 'show_card_fragment.graphql'

query AllShows($countryCodes: [String!]!, $serviceNames: [String!]!, $page: Int!) {
  shows(countryCodes: $countryCodes, serviceNames: $serviceNames, page: $page) {
     ...ShowCard
  }
}

show_card_fragment.graphql

fragment NestedFragment on Show {
  title
  posterUrl
}

fragment ShowCard on Show {
  ...NestedFragment
}

But when running the build_runner I get this error:

What am I missing here?
