I've seen a few questions on here they all seem to suggest something along the lines of node --max_old_space_size=8048. In most cases the question has highlighted the code which causes this. I can't figure out what this is. How do I find out what is causing the issue? I'd like to initially see if there's anything wrong there rather than blindly trying something.

Could having a copy of my node_modules folder in the project folder cause this in any way?
