14:53:30.935 - Unable to find module for asset id 3419556000. Does the asset have a ModuleScript named "MainModule"?

This error keeps popping up. Even when I write ZERO code in my game. It's not doing anything really, I just wanna know if anybody else has the same message. These error messages are attached to "Handler" scripts that are inserted in my game, even if I delete them, they pop back up. I'm pretty sure it's a plugin doing this and the scripts got broken. All this really does is add an error message to my output, so It's not hurtful. I'm just curious about it.
