Production outage: PHP API - Batch Processing No Longer Working

Since this morning I have not been able to execute any batched api calls.

The api usage logs show all api batch calls as status 200:
http://api.aspose.cloud/v4.0/words/batch 200

But my PHP error log shows:

Undefined property: stdClass::$Error {"exception":"[object] (ErrorException(code: 0): Undefined property: stdClass::$Error at /app/laravel/vendor/aspose-cloud/aspose-words-cloud/src/Aspose/Words/ApiException.php:93)

If I execute the same requests without using the batch api then the calls work.

Has something changed in the API ?

Sorry for the inconvenience. We are investigating this issue.
