That file is not generated by us and it terminated any other full page cache plugin. Please remove it if you don’t use it. Our plugin can generate the file automatically.

so removing it will not adversely affect my site correct? and that should solve the issue?

I am not sure if it will affect your site. You need to contact the one who generated it and see.

That file is the issue caused the notice you mentioned in OP.

Did you used to have Comet Cache on your site? Because it looks like Comet Cache created that file. If you no longer have it installed, then it should be safe to remove the file.
