MongoDB: How to deal with invalid ObjectIDs - json

Question

Here below is my code to find a document by ObjectID:
def find(selector: JsValue, projection: Option[JsValue], sort: Option[JsValue],
page: Int, perPage: Int): Future[Seq[JsValue]] = {
var query = collection.genericQueryBuilder.query(selector).options(
QueryOpts(skipN = page * perPage)
)
projection.map(value => query = query.projection(value))
sort.map(value => query = query.sort(value.as[JsObject]))
// this is the line where the call crashes
query.cursor[JsValue].collect[Vector](perPage).transform(
success => success,
failure => failure match {
case e: LastError => DaoException(e.message, Some(DATABASE_ERROR))
}
)
}
Now let's suppose we invoke this method with an invalid ObjectID:
// ObjectId 53125e9c2004006d04b605abK is invalid (ends with a K)
find(Json.obj("_id" -> Json.obj("$oid" -> "53125e9c2004006d04b605abK")), None, None, 0, 25)
The call above causes the following exception when executing query.cursor[JsValue].collect[Vector](perPage) in the find method:

Any idea? Thanks.
