how to fetch transitionNotAllowed errro message

[steven-lury]

How can I get exact errors of canTransitionTo. For example, In InitToPaid Transition, if payment is equal to invoice_amount and paid by paypal , transition is allowed.

public function canTransition()
{
return $this->invoices->isPaidByPapal() && $this->invoice->amount == $response->paid_amount && ...... ;
}
I want to find a solution which conditions doesn't satisfied the canTransition() method and return it in exception
