Description
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.
Relevant log output
Results in this error message from graph-node

Research direction
Start by reproducing the linked GraphQL query against the graph-network arbitrum subgraph and inspect the graph-node store query shown in the log, especially the join to subgraph_metadata and its block_range condition. Trace how sorting by nested metadata fields is generated; done means nested-field sorting no longer produces the missing-column error and the reported query returns results.
