Here is the complete code of my observer .

<?php
namespace Ibnab\Additional\Observer;
use Magento\Framework\Event\Observer as EventObserver;
use Magento\Framework\Event\ObserverInterface;
use Magento\OfflinePayments\Model\Banktransfer;
class SaveBankInfoToOrderObserver implements ObserverInterface {

    protected $_inputParamsResolver;
    protected $_quoteRepository;
    protected $logger;
    protected $_state;

    public function __construct(\Magento\Webapi\Controller\Rest\InputParamsResolver $inputParamsResolver, \Magento\Quote\Model\QuoteRepository $quoteRepository, \Psr\Log\LoggerInterface $logger,\Magento\Framework\App\State $state) {
        $this->_inputParamsResolver = $inputParamsResolver;
        $this->_quoteRepository = $quoteRepository;
        $this->logger = $logger;
        $this->_state = $state;
    }

    public function execute(EventObserver $observer) {
        $inputParams = $this->_inputParamsResolver->resolve();
        if($this->_state->getAreaCode() != \Magento\Framework\App\Area::AREA_ADMINHTML){
        foreach ($inputParams as $inputParam) {
            if ($inputParam instanceof \Magento\Quote\Model\Quote\Payment) {
                $paymentData = $inputParam->getData('additional_data');
                $paymentOrder = $observer->getEvent()->getPayment();
                $order = $paymentOrder->getOrder();
                $quote = $this->_quoteRepository->get($order->getQuoteId());
                $paymentQuote = $quote->getPayment();
                $method = $paymentQuote->getMethodInstance()->getCode();

                if ($method == Banktransfer::PAYMENT_METHOD_BANKTRANSFER_CODE) {
                    if(isset($paymentData['bankowner'])){
                    $paymentQuote->setData('bankowner', $paymentData['bankowner']);
                    $paymentOrder->setData('bankowner', $paymentData['bankowner']);
                    }
                    if(isset($paymentData['banknumber'])){
                    $paymentQuote->setData('banknumber', $paymentData['banknumber']);
                    $paymentOrder->setData('banknumber', $paymentData['banknumber']);
                    }
                    if(isset($paymentData['banktransid'])){
                    $paymentQuote->setData('banktransid', $paymentData['banktransid']);
                    $paymentOrder->setData('banktransid', $paymentData['banktransid']);
                    }
                    if(isset($paymentData['bankname'])){
                    $paymentQuote->setData('bankname', $paymentData['bankname']);
                    $paymentOrder->setData('bankname', $paymentData['bankname']);
                    }
                }
            }
        }

       // print_r($paymentQuote);exit;
       }
    }
}

Can any one help me on how to resolve this error?

Answer 1

You are getting error due using Magento\Webapi\Controller\Rest\InputParamsResolver.

Please update your Observer code as follows

step 1:

Update SaveBankInfoToOrderObserver.php file code as given below.

File:/app/code/Ibnab/Additional/Observer/SaveBankInfoToOrderObserver.php

<?php
namespace Ibnab\Additional\Observer;
use Magento\Framework\Event\Observer as EventObserver;
use Magento\Framework\Event\ObserverInterface;
use Magento\OfflinePayments\Model\Banktransfer;



class SaveBankInfoToOrderObserver implements ObserverInterface {

    protected $_inputParamsResolver;
    protected $_quoteRepository;
    protected $logger;
    protected $_state;
    protected $_request;

    public function __construct(
    \Magento\Webapi\Controller\Rest\InputParamsResolver $inputParamsResolver,
     \Magento\Quote\Model\QuoteRepository $quoteRepository,
      \Psr\Log\LoggerInterface $logger,
      \Magento\Framework\App\State $state,
      \Magento\Framework\App\Request\Http $request
      ) {
        $this->_inputParamsResolver = $inputParamsResolver;
        $this->_quoteRepository = $quoteRepository;
        $this->logger = $logger;
        $this->_state = $state;
         $this->_request = $request;
    }


       public function execute(EventObserver $observer) {        
         $route      = $this->_request->getRouteName();          
        if($route ==''){ 
        $inputParams = $this->_inputParamsResolver->resolve();        
        if($this->_state->getAreaCode() != \Magento\Framework\App\Area::AREA_ADMINHTML){
        foreach ($inputParams as $inputParam) {
            if ($inputParam instanceof \Magento\Quote\Model\Quote\Payment) {
                $paymentData = $inputParam->getData('additional_data');
                $paymentOrder = $observer->getEvent()->getPayment();
                $order = $paymentOrder->getOrder();
                $quote = $this->_quoteRepository->get($order->getQuoteId());
                $paymentQuote = $quote->getPayment();
                $method = $paymentQuote->getMethodInstance()->getCode();
                if ($method == Banktransfer::PAYMENT_METHOD_BANKTRANSFER_CODE) {
                    if(isset($paymentData['bankowner'])){
                    $paymentQuote->setData('bankowner', $paymentData['bankowner']);
                    $paymentOrder->setData('bankowner', $paymentData['bankowner']);
                    }
                }
            }
        }
       }
      }

    }

}

Step 2: Run DI compile

sudo php bin/magento setup:di:compile

Now you can cancel order from Frontend and backend without getting any error.

Answer 2

You may try to move the events.xml file

from

app/code/Ibnab/Additional/etc/

to

app/code/Ibnab/Additional/etc/frontend/

So the event observer observes event for frontend only.
