Error when retrieving webhook notification history through API

[wp]

I'm trying to retrieve the webhook notification history through the API via the endpoint https://apitest.authorize.net/rest/v1/notifications and am receiving the following error message every time, whether I use offsets or date range parameters.

{
  "status": 500,
  "reason": "SYSTEM_ERROR",
  "message": "Failed to get notifications.",
  "correlationId": "14e9ff3a-fa6b-4317-b902-1ece0be6df76"
}

The request is pretty simple - a GET with an authorization header - so I'm not thinking the error is on my end.  Any ideas?

@wp There appeared to be a temporary issue with the service on January 14, the day you posted your question. It has since been resolved, and we haven't seen new errors since the 14th.

Could you confirm that your notifications call now returns the expected data, please?
