Exception: alphabet must contain at least 16 unique characters

Hi
First thank you for this awesome script ! i use it for almost all my projects.

I was using this lines of code before and worked perfectly:

$hashids = new Hashids\Hashids(ENCRYPTION, 10, '0123456789');
$numbers = $hashids->encrypt($encryptit);	

Until today when he show me this error message:
Exception: alphabet must contain at least 16 unique characters

How to solve it please ?

I am using this version: 0.3.1
