I have the following message after selecting my Macintosh HD to install the downloaded macOS Sierra. I'm running a 2013 MacBook Air.

The install seems to be progressing fine, but logging this message in case others have the same problem

I had the same message, but the installation failed. Then I restarted, and ran the installation again; this time it worked, and no (null) message.
 
Have the "cannot be installed on null" message also.... My install is still running... says "about a minute left" and has for a long time. Going to just leave it sit for a few hours before I hit CANCEL.....

Mine said about a minute left for about an hour...then it gave up. But as said, after I restart everything ran fine.
 
I had a null message appear at the beginning after selecting the hard drive, but it installed fine.

Yup - I am good too. Canceled stuck install and was still on prior version of MacOS. Restarted to be safe. Then restarted the Sierra install (which I found under LaunchPad after some wasted time looking in the App Store.) Install went fine on 2nd try (No "null" message shown).
