Description

paytrail-for-adobe-commerce/Controller/Callback/Index.php

Line 45 in de5b21b

$response = $this->resultFactory->create(ResultFactory::TYPE_JSON);

$response is an object of type Magento\Framework\Controller\Result\Json, and we must use $response->setData() instead of handling it as an array.

Line 59 in de5b21b

$response['error'] = $this->processPayment->process($this->request->getParams(), $this->session);

Otherwise we will die with
main.CRITICAL: Error: Cannot use object of type Magento\Framework\Controller\Result\Json\Interceptor as array in /vendor/paytrail/paytrail-for-adobe-commerce/Controller/Callback/Index.php:59
