Invalid pass number (1) for Graphics.Blit (Material "PostFX - Eye Adaptation" with 1 passes)

Hi. I played with post procesing behaviour. Everything worked fine but when i change one type of tree, i geting spam of this error: Invalid pass number (1) for Graphics.Blit (Material "PostFX - Eye Adaptation" with 1 passes) What this mean? I can't find any solution. Please Help me, i don't know why this happening. When i turn off Eye Adaptation errors stops reporing. Thanks you.
