Paymill\Models\Request\SofortChecksum customer_email parameter is missing

[Voltash]

Parameter customer_email is mandatory and needs to be added to Paymill\Models\Request\SofortChecksum

Unfortunately I need to confirm this bug. I have the same Problem, Sofortüberweisung does not seem to work at the moment.

I had some temporary success by adding a hack:

$parameter['customer_email'] = $parameter['client_email'] ?? null;

to: vendor/paymill/paymill/lib/Paymill/Request.php#237

but it is not working persistently.

I also ran into this issue, my "fix" is to add this subclass in my code:

class MySofortChecksum extends \Paymill\Models\Request\SofortChecksum {
  public function parameterize($method) {
    $parameterArray = parent::parameterize($method);
    if('create' == $method) {
      if ($this->getClientEmail()) {
        $parameterArray['customer_email'] = $this->getClientEmail();
      }
    }
    return $parameterArray;
  }
}
