Graphql query from array object

Question

I have a mongoose schema like this:

var MoviesSchema = new mongoose.Schema({
  name: String,
  collections: [String]
});

var Movie = mongoose.model('Movie', MovieSchema);

I'm using graphiti to generate the graphql schema automatically. I'm able to query the data using name, however I'm unable to query using collections since the type is an array.

For instance, this works:

{
  movies(name: "Kabali") {
    name,
    collection
  }
}

however this doesn't work:

{
  movies(collection: "Hollywood") {
    name,
    collection
  }
}

Actually, the movies field doesn't even have the argument called collection.
