I have created set of YouTube Reporting API jobs for a YouTube channel. The jobs were created and run every day as scheduled. However when I go to download the jobs they are all blank, only the header is displayed.
I checked the YouTube Reporting API job data from 3 days ago, and all the data was blank.
On the YouTube Analytics screen of YouTube Studio, data for the same day was able to be obtained.
I also checked the OAth2 authentication associations and channels, and there were no errors in the settings.

Why might my reports be empty and how can I fix this?

I downloaded data from 3 days ago using the Windows curl command.
As a result of running the command, only the header is displayed and all data is blank.
