- [x] Recreate the issue after disabling all extensions
- [x] Simplify your code around the issue to better isolate the problem

• I have a dummy project on a public repo in order to show and reproduce this strange behavoiur.
• This project has all it's configuration related files inside a ./config folder under the root folder.
• VSCode shows errors related to type declarations that are not actually present when ./config/tsconfig.json file is under the ./config folder
  • As soon as this file is moved to the root folder and it's references are properly modified, these "errors" dissapear.
• These errors do not seem to be actual errors: tsc runs fine and the app seems to run just fine in the browser with no messages whatsoever.

Steps to reproduce:

1. Clone this repo: https://github.com/HarTstaRx/errors-test.git
2. Open VSCode as admin with extensions disabled
3. Run pnpm i
4. Run pnpm build
5. Open a *.tsx file, there are errors that seem to not be actually present
   • This is a Vite + React + Typescript project : React v18.2, Typescript v4.9.5, Vite v4.1.0
   • In React there is no need anymore to import React as a global variable in order to write jsx code.
   • The list of problems are fixed when ./config/tsconfig.json file is moved to the root folder.

Duplicate of #33094

As a workaround, can you create root level tsconfig that extends your config/tsconfig.json file?

[HarTstaRx]

Thanks for finding the duplicate @mjbvz, I didn't saw it on my search so sorry for that.
Yes, I can create a root level tsconfig but that defeats the purpouse of the situation. It seems this issue has been around since several years and once was marked as priority. Is there something I can do to help with this issue?
