Question

What is the error during loading results: "Query timeout expired in method { call DocumentsStatistic_CalculateForBatch(?) }"

Even this is an error, the status is succeeded.

Answer

This message reports the timeout of one of the procedures related to the database query.
There are different possible reasons for the issue.
It may be something external (for example, another external activity was launched and it caused a small slowing down of the system).
Or it was the moment when in FlexiCapture the cleanup procedure was launched.
This message is not causing any consequences.
