Failed to build a GraphQL list result for field Project.Itemsat pathproject.items.\nExpected #<BatchLoader::GraphQL:0x000055f6101402b0 @batch_loader=#BatchLoader:0x62120>(BatchLoader::GraphQL) to implement.eachto satisfy the GraphQL return type[Item!].\n"

field :items, [Types::ItemType], null: true

def items
BatchLoader::GraphQL.for(object.id).batch(default_value: []) do |project_ids, loader|
Item.where(project_id: project_ids).each do |data|
loader.call(data.project_id) { |memo| memo << data }
end
