    Description

      It is possible during FCV upgrade/downgrade in sharded clusters, different shards are in different FCV. If a resharding is in progress, the shard in higher FCV can send $requestResumeToken queries to shards in downgraded FCV and get rejected, resulting in unrecoverable error.
