CyberSource.Client.ApiException: Could not convert string to integer: MerchantACS. Path 'consumerAuthenticationInformation.acsOperatorID', line 1, position 1948.
   at CyberSource.Client.ApiClient.Deserialize(RestResponse response, Type type)

The error only occurs if the following consumer authentication information is added

{
  "consumerAuthenticationInformation" : {
      "returnUrl": "{{returnUrl}}",
      "referenceId": "{{referenceId}}"
  }
}

If that consumer authentication information is not present, it does not fail, but since there is a PENDING_AUTHENTICATION, there is no ACCESS_TOKEN
