dnfdragora cryptic error: 'NoneType' object has no attribute 'installed'

I tried to update Fedora 32 and did not realize that my ISP DNS was down. dnfdragora gave the following cryptic backtrace. It doesn't say anything about DNS nor the network. This type of error message brings Fedora Linux closer to parity with Windows NT. ;)

Code:Error occurred:
