      Summary

      Serializer resolution in MongoDB.Driver 3.7.1 fails when using AddToSet to target a dictionary‑based nested collection path. The driver now requires serializers implementing IBsonArraySerializer for paths like "Buckets.<key>", whereas earlier versions (3.6.x) accepted IEnumerable<T> without issue.
