Inconsistent Empty PDF when converting Word or Excel to PDF

We use the Aspose Cloud service for Words and Cells to convert either of these to PDF. Unsure if this is the correct category to post to, doesn’t seem to separate on-premises from cloud services.

On roughly 12% of requests we receive an empty PDF as a response instead of the converted document. We’ve noticed that in our tracing, the Dotnet Core SDK is receiving a 401 response, then requesting a new token and then sending the convert request again and this is when the empty result is returned. No indication of failure is included, it’s essentially a successful request but the PDF is empty.

From our telemetry we have seen that this only occurs when the 401+Token request takes place, when this is not done, then requests convert correctly.

The same document with succeed when attempting to convert at a later point, so the issue is not related to document contents.

Anyone seen a similar issue?
