subscriptionBillingAttemptCreate returning a null subscriptionBillingAttempt

Does anyone know why subscriptionBillingAttemptCreate would be returning a null subscriptionBillingAttempt? This is for several active contracts that have been billed without any issue in the past. I can’t seem to find anything in the documentation about a null response.

{
  "subscriptionBillingAttemptCreate": {
    "subscriptionBillingAttempt": null
  }
}

Hi!

To get more details you should also query the userErrors field on this mutation.

Oh, duh, thank you! That gave me what I needed. Much appreciated!
