Describe the issue

First, note that my project's automated tests were working a few months back, so to me it looks like something changed on Mollie side.

Problem is that mandateId is not returned in a payment create response. Here's my request:

 {
    "amount": {
        "currency":"CHF",
        "value":"0.00"
    },
    "customerId":"cst_VWkTu3hcYy",
    "sequenceType":"first",
    "description":"Auto-Payment Setup",
    "webhookUrl":[removed],
    "redirectUrl":[removed],
    "locale":"en_US",
    "method":"creditcard"
}

The response is:

array(
   'resource' => 'payment',
   'id' => 'tr_uNKTAEXoFC',
   'mode' => 'test',
   'createdAt' => '2022-11-18T09:50:58+00:00',
   'amount' => (object) array(
     'value' => '0.00',
     'currency' => 'CHF',
  ),
   'description' => 'Auto-Payment Setup',
   'method' => 'creditcard',
   'metadata' => NULL,
   'status' => 'open',
   'isCancelable' => false,
   'expiresAt' => '2022-11-18T10:05:58+00:00',
   'locale' => 'en_US',
   'profileId' => 'pfl_vDwxAnGg2Q',
   'customerId' => 'cst_VWkTu3hcYy',
   'sequenceType' => 'first',
   'redirectUrl' => [removed],
   'webhookUrl' => [removed],
   '_links' => [removed]
)
