openssl_encrypt (IV) error

I got this error when trying this code $encrypted = Encryption::php()->encrypt($value); :

openssl_encrypt(): Using an empty Initialization Vector (iv) is potentially insecure and not recommended
vendor / maize-tech / laravel-encryptable / src / PHPEncrypter.php : 82

I found the potential reason here :

Am i doing something wrong ? or is it a real issue ?
