Problem & expected behavior (under 200 words)

1. Run the application with pnpm dev works fine.
2. Add a breakpoint and launch with the provided launch.json, see that you get an error:

node:internal/modules/run_main:122
    triggerUncaughtException(
    ^
Waiting for the debugger to disconnect...

It seems like when I use the default launch.json file provided in the docs:

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "tsx",
      "type": "node",
      "request": "launch",
      "program": "${file}",
      "runtimeExecutable": "tsx",
      "console": "integratedTerminal",
      "internalConsoleOptions": "neverOpen",
      "skipFiles": ["<node_internals>/**", "${workspaceFolder}/node_modules/**"]
    }
  ]
}

It does not work as it does not read the paths from tsconfig.json. However, if I add this, it works:

"runtimeArgs": ["--tsconfig", "${workspaceFolder}/tsconfig.json"],

So I guess, either that could be included in the docs, or tsx needs to be updated somehow.

Bugs are expected to be fixed by those affected by it

• I'm interested in working on this issue

Compensating engineering work will speed up resolution and support the project

• I'm willing to offer $10 for financial support

tsx detects the tsconfig from the CWD

Are you able to set that in the launch config?

Yeah, adding "cwd": "${workspaceFolder}" worked as well.

Forgot to mention it, but I use nvim with LazyVim, with more or less the default settings. So I assume all LazyVim users at least will have this if they do not add one of the two attributes.
