This test hits an edge case bug where queries on timeseries with $lookup and $graphLookup stages where the inner and outer collection are the same will fail during concurrent FCV upgrades/downgrades. The error raised is IllegalChangeToExpectedShardVersion when we try to attach a cursor for local read here. I think the error is meant to be caught by tryAttachCursorSourceForLocalRead but it propagates up the routing context and ultimately fails the aggregation.
