Task details via API no longer returning array of task owners

Task details via API no longer returning array of task owners

Until today, we had no problem with the task details API call.  

Today, when we call for all task details for a particular task, the API is not pushing any data to the "details" object, where the "owners" array has always been stored before.  All other values we expect outside of "details" are being returned as normal and without flaw.  But the "details" object is simply empty.

Has there been a change in the API?  The docs don't reflect any intended change.  

Perhaps this is a short-term bug?  If so, we rely on this heavily and hope it can be fixed soon.

For quick reference, we are using this call:  https://www.zoho.com/projects/help/rest-api/tasks-api.html#alink3
