Not easy to debug error only in dev mode

[emersonbottero]

Describe the bug

The build and serve commands works but the dev doesn't.

Reproduction

clone the repo

• yarn build (you will get some post build error because I'm transitioning the documentation to vitepress)
• yarn vdocs:build
• yarn vdocs:serve (it works normally)
• yarn vdocs:dev (it will thrown an error)

The error thrown is misleading in my opinion..

Uncaught TypeError: Cannot read properties of undefined (reading 'accept') at VPSkipLink.vue:37:3

Expected behavior

the error should point to the correct file? I'm sure is not a problem in VPSkipLink file. Is hard to debug without knowledge of vitepress internal logic

Additional context

I'm convincing the mermaidjs team to update their documentation to use vitepress 😁. I created a repo from scratch first and it works without problem but in the mermaid repo this error may be a combination of the setting done in packaeg.json and tsconfig but!

I think we really want anyone to be able to use vitepress to update any library out there (mission inspiration?? 😅)

@brc-dd I am still having the same error, my file structure:

config.ts is empty, index.md has just a demo message: # Hello world I think by default it should show whatever inside index.md file but after starting the server an empty page shows with the same error: my packages versions:

    "vite": "^3.1.2",
    "vitepress": "^1.0.0-alpha.16",
    "vue": "^3.2.39"

is there something missing, or wrong I am doing?

[emersonbottero]

@yaman3bd it has not been published yet.. wait for the next vite release!

[emersonbottero]

@brc-dd I'm still getting the same error. You can update vitepress and vite in the mentioned repo to see the problem.

[brc-dd]

I haven't released a new version yet.

Weird, not working on alpha-18 too :/

Ah, this will be fixed in next version of @vitejs/plugin-vue
