[Bug] Sorting subgraphs by nested FDS field throws error

Bug report

Querying the graph-network arbitrum subgraph and sorting by metadata__displayName; throws an error (see log output).
There was a recent change to the network subgraph to support File Data Services; this change moved the displayName field from the top-level Subgraph entity to be in a nested SubgraphMetadata entity that is controlled by FDS.
Sorting by any field in the metadata entity throws this error.

まず、リンクされた GraphQL クエリを graph-network の arbitrum subgraph に対して再現し、ログに表示される graph-node のストアクエリを調査します。特に、subgraph_metadata への join とその block_range 条件を確認してください。ネストされたメタデータフィールドによるソートがどのように生成されるかを追跡します。完了条件は、ネストされたフィールドによるソートで missing-column error が発生しなくなり、報告されたクエリが結果を返すことです。
