Shot in the dark:
My first guess is a buggy third-party plug-in. But that's just a guess. If I were in your position, I'd try disabling effects one by one and see if doing so made the error go away.
I only have one effect in that precomp adjustment layer. With both CC Lens or Transform, I'm getting the error.
Can you post a copy of your project?
I was about to post the file, but now the problem has vanished. More AE gremlins!
