Any ideas? Thank you

I’m getting this and have tried stripping out plugins to narrow it down, but I’m not getting anywhere with it. Is there a way to run vite-ssg with an active debugger on so I can step through the code and extract what is causing it? UPDATE: I went ahead and just added console log statements to the dependency files. Found out it was unresolved components, but were unresolved because I was removing plugins to find what the original error was; so I may update again. UPDATE2: The culprit was the order of my plugins… I really wish Vue would give better error output.
