      const encryptSchema = {
          $jsonSchema: {properties: {_id: {encrypt: {}}}}
      };
      const collName = "repro";
      db.createCollection(collName, {validator: encryptSchema, validationAction: "error"});
      assert.commandFailedWithCode(db.runCommand({collMod: collName, validationAction: "warn"}),
                                   ErrorCodes.QueryFeatureNotAllowed);
      print(tojson(db.runCommand({validate: collName, full: true})));
      

      The above script will produce the following error:
      "stored value for validation action does not match cached value: error != warn"

      See 'steps to reproduce'. Basically, if the validationAction or validationLevel is set, but an error is thrown upon reparsing the validator, the value of CollectionImpl::_validationAction' or 'CollectionImpl::_validationLevel' never gets set back to its original value. This leads to the in memory value of validationAction/level not matching the on disk value.
