## Problem The aggregation framework's GraphQL `orderBy` argument cannot sort by parameterized dimensions (e.g., `date_bucket` dimensions with granularity parameters). Attempting to order by a parameterized dimension results in: ``` "message": "the specified identifier is not available: 'eventDate'" ``` ## Example This query fails: ```graphql orderBy: [{identifier: "eventDate", direction: DESC}] ``` When `eventDate` is defined as: ```ruby date_bucket :event_date, :date, -> { sql('date') }, parameters: { granularity: { type: :string, in: %w[daily weekly monthly] } } ``` ## Root Cause 1. `AggregationOrder` input type lacks a `parameters` field 2. Order configuration matching doesn't handle parameter normalization (case conversion and hash key types) ## Solution Resolved in [!223108](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/223108)
