PLS-00584: size of an opaque type must be between 1 and 4000 bytes

Cause: An attempt was made to specify an explicit size for an opaque type, but the specified size was out of the valid range.

Action: Change the explicit size to be between 1 and 4000 bytes, or change the declaration to be varying-length without an explicit size.
