app doesn't always return pspReference for XX_FAILURE responses, only when there wasn't a pspReference in a response from Adyen or an error was caused by internal app error handling
app returns XX_ACTION_REQUIRED when there is no pspReference in the response from Adyen, response with action object might include a pspReference and it might be mapped to other response type

in a response from Adyen or an error was caused by internal app error handlingXX_ACTION_REQUIRED
when there is nopspReference
