      If I create a collection with validationLevel: strict and validationAction: warn, and subsequently run db.collection.validate() on a collection containing invalid documents, I would expect the number of invalid documents and the warnings array to be populated

      However, running `db.collection.validate()` on a collection with invalid documents returns unexpected results:

      • nInvalidDocuments is 0
      • and no messages present in the warnings[] or errors[] array

      The logs for the server do log the errors, but the errors are not reflected in the output to db.collection.validate().

      If I use validationAction: error, then execute `db.collection.validate()`, there is a warning present in warnings[] but nInvalidDocuments is still 0.
