Defined in:
lib/rubocop/cop/graphql/default_null_true.rb

Overview

Identify (and auto-correct) any field configuration which duplicates the default null: true property.

null: true is default because nullable fields can always be converted to non-null fields (null: false) without a breaking change. (The opposite change, from null: false to null: true, change.)

Both of these define name: String in GraphQL:

bad

field :name, String, null: true

good

field :name, String
