Sourcemap for "X.ts" points to missing source files

[michealroberts]

Describe the bug

I currently have the following configuration for my Vite & Vue.js project:

import { defineConfig } from 'vite'

import vue from '@vitejs/plugin-vue'
import WindiCSS from 'vite-plugin-windicss'

import typescript from '@rollup/plugin-typescript'

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [
    // https://github.com/antfu/vite-plugin-windicss
    WindiCSS({
      safelist: '',
    }),
    typescript({
        tsconfig: './tsconfig.json'
    }),
    vue()
  ]
})

And on running the following command:

npm run dev -- --host --port 8099

And navigating to localhost:8099 in the browser I am seeing these errors:

Sourcemap for "/Users/michael/Developer/observerly/aestrium/src/main.ts" points to missing source files
Sourcemap for "/Users/michael/Developer/observerly/aestrium/src/components/index.ts" points to missing source files

Sourcemap for "/Users/michael/Developer/observerly/aestrium/src/utils/canvas.ts" points to missing source files
Sourcemap for "/Users/michael/Developer/observerly/aestrium/src/utils/intersectDistance.ts" points to missing source files

Although the app works 100% fine, I believe these are just warnings.

I've looked through the documentation as to why this could be happening, but nothing suggests why. There is a build.sourcemap flag I could add, but no dev.sourcemap (a similar one exists for CSS css.devSourcemap) ...

Is this related to the following PR: PR 7442 ? I have recently updated to the most recent version but I am guessing these changes haven't been added to a release yet?

[sapphi-red]

Your reproduction links to 404. It seems it is a private repository.

Let me know if you want access to it I can add you as temp maintainer.

[sapphi-red]

If it is not a minimal reproducible example, could you create it?

[michealroberts]

If it is not a minimal reproducible example, could you create it?

It's a maximum reproducible example ... i.e., the actual code base with the error.

[github-actions[bot]]

Hello @michael-observerly. Please provide a minimal reproduction using a GitHub repository or StackBlitz. Issues marked with need reproduction will be closed if they have no activity within 3 days.

[bluwy]

@michael-observerly We need a minimal repro so that it's simpler to debug what causes the issue. A full scale app as a repro could introduce a lot of places to look for, making it hard to resolve the issue.

[michealroberts]

@bluwy Ok, I will get a MRE to you. However, there is no Vite + Vue 3 project on Stackblitz out of the box ... do you know of a stable fork to share for Vite version 2.9.1?

[michealroberts]

@bluwy Would you be happy if I started from a template I've just created: https://stackblitz.com/edit/52908eea-914c-4188-9920-784a3a0d8eb3-du2mmh

[bluwy]

The template looks good to me. There is a Vite + Vue 3 template though:

Closing this issue as setting the sourceMap flag in tsconfig.json seems to remove the error:

{
    "compilerOptions": {
       "sourceMap": false,
    }
}
