Drupal 8 Commerce: Fixing 'No Such Customer' error on checkout

Posted on 15th August 2018

Recently I was experiencing an issue on the Drupal 8 website I’m working on, where a small number of users were not able to complete the checkout process and instead got a generic The site has encountered an unexpected error message.

Looking at the log, I was able to see the error being thrown (the customer ID has been redacted):

Stripe\Error\InvalidRequest: No such customer: cus_xxxxxxxxxxxxxx in Stripe\ApiRequestor::_specificAPIError() (line 124 of /var/www/vendor/stripe/stripe-php/lib/ApiRequestor.php).

Logging in to the Stripe account, I was able to confirm that the specified customer ID did not exist. So where was it coming from, and why was Drupal trying to retrieve a non-existent customer?


After some investigation, I found a table in the database named user__commerce_remote_id which stores the remote customer ID for each payment method (again, the customer ID has been redacted).

The entity_id and revision_id values in this case refer to the user that the Stripe customer has been associated with.

As there was no customer in Stripe with this ID, I think that this must be a customer ID from the test environment (the data from which was deleted before the site went live).

Drupal code

This I believe is the Drupal code where the error was being triggered:

// modules/contrib/commerce_stripe/src/Plugin/Commerce/PaymentGateway/Stripe.php

public function createPayment(PaymentInterface $payment, $capture = TRUE) {

  $owner = $payment_method->getOwner();
  if ($owner && $owner->isAuthenticated()) {
    $transaction_data['customer'] = $this->getRemoteCustomerId($owner);

  try {
    $result = \Stripe\Charge::create($transaction_data);
  catch (\Stripe\Error\Base $e) {


Stripe code

I can also see in the Stripe library where the original error is generated.

private static function _specificAPIError($rbody, $rcode, $rheaders, $resp, $errorData)
    $msg = isset($errorData['message']) ? $errorData['message'] : null;
    $param = isset($errorData['param']) ? $errorData['param'] : null;
    $code = isset($errorData['code']) ? $errorData['code'] : null;

    switch ($rcode) {

        case 404:
            return new Error\InvalidRequest($msg, $param, $rcode, $rbody, $resp, $rheaders);



After confirming that it was the correct user ID, simply removing that row from the database allowed the new Stripe customer to be created and for the user to check out successfully.
