Expected result

Actual result

[Screenshot, logs]

I have spend too much time on this and at last I have concluded that in the ResponseValidator.php file line number 56 throw new LocalizedException(__('Transaction has been declined'));
throw an error. Code is working before this line and after this line it is throwing server error.
There seems to be a bug with LocalizedException in magento 2.
Can anyone let meknow the solution for this?

vendor\magento\module-paypal\Model\Payflow\Service\Response\Validator\ResponseValidator.php
public function validate(DataObject $response, Transparent $transparentModel)
{
switch ($response->getResult()) {
case Payflowpro::RESPONSE_CODE_APPROVED:
case Payflowpro::RESPONSE_CODE_FRAUDSERVICE_FILTER:
foreach ($this->validators as $validator) {
if ($validator->validate($response, $transparentModel) === false) {
throw new LocalizedException(__('Transaction has been declined'));
}
}
break;
case Payflowpro::RESPONSE_CODE_INVALID_AMOUNT:
break;
default:
throw new LocalizedException(__('Transaction has been declined'));
}
}

Clear Description Format is valid

@sunilwebcreation,

if ($validator->validate($response, $transparentModel) === false) {

What is the response and why it does not pass validation?

I have this problem on Magento 2.2.2. I haven't seen the PHP errors but my problems are exactly the same. I can provide information about the website I'm working on (we're pre-production) including passwords that you can use to access the various things that you need. Please let me know what is a secure way to get you this information.

@magento-engcom-team Is anyone interested in following up on this issue? I haven't heard a thing & we're still stuck.

@rheckart same question to you then: https://github.com/magento/magento2/issues/14283#issuecomment-375657027

Try to log some information on your site and post it here.

I have Debug Mode set to Yes under Advanced Settings in PayPal Payflow Pro. Where do those logs get written to? I'm looking in /var/logs, but debug, exception and system.log don't seem to have any payment process information in them.

Hi @magento-engcom-team

I have now go into deep and noticed that the below line is creating issue.
vendor\magento\module-paypal\Model\Payflow\Service\Response\Validator\ResponseValidator.php
_throw new LocalizedException(('Transaction has been declined'));_

when I print some text before this line then its works but when I print some text after this line then it return error message.

Further if I remove keyword throw i.e
_new LocalizedException(('Transaction has been declined'));_
then it print the text.

Please suggest.

any solution?

@mariamghalleb, this is how I got around solving the issue:

You may echo the actual error message on this file: vendor/magento/module-payment/view/frontend/templates/transparent/iframe.phtml if you have not extend the file yet. If you have, you may edit this file: app/design/[vendor]/[theme]/ go to line 42 and replace this

message: $t('An error occurred on the server. Please try to place the order again.')

with this
`message: $t('<?php echo $params['error_msg'];?>')`

Editing iframe.phtml seems to work above. However, the error message is still not descriptive enough. When the card fails an AVS check, the $params['error_msg'] message returns a message about the transaction being declined but it doesn't indicate it's an AVS problem.

If I do an inspect on the page, and view the network tab, I can see that paypal is returning a variable called RESPMSG and the value is:

RESPMSG: Failed AVS Check: 10554-The transaction was refused.

I would like to print this error if possible so people know they just need to update the address, and it's not a card decline issue.

I'm actually really surprised by this - anybody using paypal as their payment processor is currently getting the message "An error occurred on the server. Please try to place the order again." whenever there's a problem with the credit card? That seems really bad.

@ArbyLeon The errors seem more user friendly now,
does your solution cause any problems?

Thank you !

mariamghalleb on 10 May 2018

@djview ,

You're right! It's not descriptive enough,
But do you think it has to be that descriptive? from my experience online (as a user) the errors are never that detailed!

But I do still agree, maybe Magento should fix this? ...

mariamghalleb on 10 May 2018

@mariamhalleb,

it is important to know what the issue is if the issue is from our end and not the customer, which was the case for us. I understand the security risks as you’re exposing the system. Therefore, I would only keep it this way for a short time.

Also, I think the error is descriptive enough to know the general direction of the issue. IMO, being too descriptive might cause security risks.

ArbyLeon on 10 May 2018

I guess I always thought it was useful if customers knew the billing address was not matching the card (AVS error) vs the card declining. What do other people think? Is that a security risk? The problem with editing this file is the same message is displayed on the front end AND the backend. It would be nice to display the full message in the admin area at the very least, and then display some more user friendly messages in the front end.

hey @sunilwebcreation,
i am also facing exact same issue. I have also spend too much time on this and not got any solution.

@balwant20 According to this community post that I created & PayPal's response, PayPal needs to set up Reference Transactions on their end for your account. I am still waiting for them to enable this to test it. These are the instructions I received:

Thank you for contacting PayPal Merchant Technical Support. I am happy to assist you with the Magento 2.2.2 integration.

Please follow these steps to adjust the settings in your manager account.

Login to manager.paypal.com and click Service Settings

Select “Set Up”

Toggles on this page include:
a. Transaction Process Mode > Live
b. Return URL Method > POST
c. Check CSC boxes under Billing Information for both required and editable fields
d. CSC > No
e. AVS > No
f. Enable Secure Token > Yes

Click “Save Changes”

Go to Service Settings > Customize
a. Select Layout C > Save and Publish (this avoids a bug that occurs on some accounts for
transparent redirect)

Click “Account Administration”
a. Click “Transaction Settings” under Manager Security header
i. Set “Allow Reference Transactions” to “Yes”

Reference transactions need to be enabled on your PayPal account as well, which I have submitted a ticket for. You will receive an email notification when this is complete.

Please let me know if you have further questions or if the issue has been resolved so I can close your support ticket appropriately.

Sincerely,

Alex
Global Technical Support
PayPal, Inc.
