"Task exception was never retrieved" error on startup

Hello, I recently made a fair amount of changes to my HA configuration and ever since then I get the following error in my log files when I restart HA. Can someone point me in the right direction of what I did or what I need to change to resolve it? I’m running HA 0.78.1

Solved! I just saw that there was a 78.2 release so I updated to it and no more error.
