Details

When using rsdoctor with tanstack-router plugin, server won't be up even if build completed. And when switching to the brief mode, got the following log

TypeError: Converting circular structure to JSON
    --> starting at object with constructor 'Compiler'
    --- property 'root' closes the circle

Sorry, I couldn't reproduce this issue. Did I do something wrong? I followed the steps above, and didn't encounter the error in the brief.

node: 22, pnpm: 10.11.1

@easy1090 Sry for the late reply because of my busy work. It looks like your env is mac, and I just tried it on my Mac and found that I could not reproduce this issue either. So maybe this is a windows specific issue? Do u have a windows environment? Maybe you can try it on windows.

Ok 👌🏻

After investigation, the reason is that the tanstack package includes the unplugin npm package, which contains rspack/loader/transform.js. The loader’s options include a compiler, which causes a circular reference error when using JSON.stringify. You can temporarily disable this loader, and on my end, I can skip this error.

However, I found that even on Mac, only the builtin loader is analyzed, which is not comprehensive. The issue of incomplete loader analysis needs to be looked into further.
