Hello @rajkumar_ghosh 

vendor\magento\module-checkout\Model\PaymentInformationManagement.php

check line no 83 

 try {
            $orderId = $this->cartManagement->placeOrder($cartId);
        } catch (\Magento\Framework\Exception\LocalizedException $e) {
            throw new CouldNotSaveException(
                __($e->getMessage()),
                $e
            );
        } catch (\Exception $e) {
            $this->getLogger()->critical($e);
            throw new CouldNotSaveException(
                __('An error occurred on the server. Please try to place the order again.'),
                $e
            );
        }

check is that going into the catch

Hello,

I am not able to see your screenshot.

Have you did echo and exit that file

You need to do little debug there

Hi Sunil,

I do this ,Please check this below code.

try {
           $orderId = $this->cartManagement->placeOrder($cartId);
           echo $orderId;
           exit;
        } catch (\Magento\Framework\Exception\LocalizedException $e) {
            throw new CouldNotSaveException(
                __($e->getMessage()),
                $e
            );
        } catch (\Exception $e) {
            $this->getLogger()->critical($e);
            throw new CouldNotSaveException(
                __('An error occurred on the server. Please try to place the order again.'),
                $e
            );
        }

But nothing response found from payment-information API call.

Hello sunil,

I have a old project backup.I install this backup into another server and checked order id comes into the response in payment-information API. So may I restore the vendor and app folder into the current project.This way I get the solution.
Please reply it is very important.we need solution as soon as possible.
