ORA-21560: argument string is null, invalid, or out of range

ORA-21560: argument string is null, invalid, or out of range
Cause: The argument is expecting a non-null, valid value but the argument value passed in is null, invalid, or out of range. Examples include when the LOB/FILE positional or size argument has a value outside the range 1 through (4GB - 1), or when an invalid open mode is used to open a file, etc.
Action: Check your program and correct the caller of the routine to not pass a null, invalid or out-of-range argument value.
