Unfortunately that can be a common error in logs. It doesn't (usually) indicate a problem or bug, just an unfortunate situation.

Liquidations are a competitive environment, so there are a bunch of other liquidators all trying to liquidate the same accounts the moment they become liquidatable.

When this happens, sometimes a liquidator tries to liquidate an account but another liquidator successfully liquidated it just before. When that happens, the second liquidator receives that NotLiquidatable error you saw.

There's nothing wrong with what you're doing, someone else was just smarter, faster, or luckier that time. Sorry it's not better news.
