Bank callback error and the payment status did not get to drupal site

Hi,

Thank you for the great module. And happy new year!

I had this error that I can see in the bank system:

https://www.domain.com/es/sermepa/callback
-1 java.lang.ArrayIndexOutOfBoundsException

There was nothing happened even the client payment successfully proceeded. I cannot receive the response from the bank. Anyone knows where do I did it wrong? any advice to know the issue.

Thank you.
