+ * - `DocumentNotFoundError`: The document you tried to [`save()`](document.html#document_Document-save) was not found
+ * - `ValidatorError`: error from an individual schema path's validator

+ * - `ObjectParameterError`: Thrown when you pass a non-object value to a function which expects an object as a paramter
