production.log flooded with complexity_cost_calculation_mode

Overview

gitlab-rails production.log is getting flooded with this message:

GraphQL-Ruby's complexity cost system is getting some "breaking fixes" in a future version. See the migration notes at https://graphql-ruby.org/api-doc/2.5.11/GraphQL/Schema.html#complexity_cost_calculation_mode_for-class_method

To opt into the future behavior, configure your schema (GitlabSchema) with:

  complexity_cost_calculation_mode(:future) # or `:legacy`, `:compare`

Implementation

• Set cost_calculation to legacy to avoid any breaking behaviours.
