[🐛 Bug]: Adding dynamic routes explodes bundle size#932

### next-on-pages environment related information it gets ran on pages, not locally. ### Description Adding routes to my project increased bundle size from 3KB to 28MB. By route, I mean a structure in the App router such as "/farm/[farmId]". The build size is acceptable (about 2mb). Next-on-pages then tacks on massive *.func.js files. Here are some build logs, showing an increase from 3KB to 9MB (after adding the first few routes). No major changes to the site were made besides routes.
