RoR Graphql Types::BaseObject NameError

When making a graphql API request to my rails backend I get the following error in my app/graphql/types/query_type.rb:

Started POST "/graphql" for 127.0.0.1 at 2023-04-06 13:27:07 +0200Processing by GraphqlController#execute as */*  Parameters: {...}Completed 500 Internal Server Error in 266ms (ActiveRecord: 0.0ms | Allocations: 3660)NameError (uninitialized constant Types::BaseObject):app/graphql/types/query_type.rb:2:in `<module:Types>'app/graphql/types/query_type.rb:1:in `<main>'...

This is the QueryType class:

module Types  class QueryType < Types::BaseObject    field :discord_user, DiscordUserType, null: true do      argument :id, ID, required: true    end    def discord_user(id:)      DiscordUser.find(id)    end    field :discord_users, [DiscordUserType], null: false    def discord_users      DiscordUser.all    end  endend

I myself did not find an error with the naming conventions and since the BaseObject is provided by the graphql gem I don't know why there should be an error with it.
