Graphql cannot provide nested pokemon species

It seems like the graphql API is unable to provide a pokemon species data when nested under pokemon -> pokemonspecy.

This query returns an empty array as pokemon_v2_pokemonspecies

query samplePokeAPIquery {
  pokemon_v2_pokemon(where: {name: {_eq: "charizard"}}) {
    name
		pokemon_v2_pokemonspecy {
			pokemon_v2_pokemonspecies {
				name
			}
		}
  }
}

This query returns a valid response (but requires a separate query).

query samplePokeAPIquery {
  pokemon_v2_pokemonspecies(where: {id: {_eq: 64}}) {
    base_happiness
    capture_rate
    id
  }
}

Start by running the nested and separate GraphQL queries from the issue and compare their responses. Trace the relationship between pokemon_v2_pokemon and pokemon_v2_pokemonspecies in the GraphQL API; done when the nested query returns the species data for Charizard instead of an empty array.
