Please remove else in your getInputFilter method. I think this is what caused the error. This is why you got the error : null given, the $inputfilter is never returned the first time.
I corrected it for you. Replace your method by this one :
public function getInputFilter(){
if (!$this->inputFilter) {
$inputfilter = new InputFilter();

'name' => 'name',
'required' => true,

'max' =>30,
