# New error codes added to `fileUpdate` mutation

As of API version **2023-07** new error codes `FILENAME_ALREADY_EXISTS` and `INVALID_FILENAME` will be added to the `fileUpdate` mutation. These error codes are returned when you attempt to update the filename (URL Handle) and the input either matches an existing filename (URL Handle) or it is invalid.
