ignore this file not found error dialog in illustrator

I am getting this error while running a script via Python tool but if i click ok the tool is working fine but i didn't know the source of this error in tool unable to figure it out both in illustrator or python tool. So I ish to ignore this error but this error is arriving before opening the illus javascript tool. So Suggest a way to ignore this error or tell why this error is popping up even when the tool path were correct and perfectly working fine !
