Example of log.txt in case of partial export for Network Export Data API (Yammer)

Question

According to the documentation here https://learn.microsoft.com/en-us/rest/api/yammer/network-data-export there might be partial export in the Network Export Data API

The documentation says:

"If there are errors exporting any data, the data export will be a partial export. In this case, the log.txt will contain details of what failed to export. The best way to avoid partial failures is to export smaller timeframes at a time. Large data exports are more likely to fail"

I was wondering how the log.txt looks like in case of partial export, as I have to detect that event programmatically. However there are no examples online and I was unable to reproduce the issue. Do you have any example of log.txt in case of partial export?
