Path Alias Not Working in Bun Project Despite Correct Configuration

I config path alias following this guide: https://bun.sh/guides/runtime/tsconfig-paths. But it’s not work

I create a Bun project (I’m planning to migrate a Node app to Bun) by these steps:

1. mkdir bun-test && cd bun-test && bun init

2. After init project, I add to tsconfig.ts

{
  "compilerOptions": {
    ...
    "baseUrl": "./src",
    "paths": {
      "config": ["./config/appConfig.ts"]
    }
  }
}

3. Create src/config/appConfig.ts

export default {
  message: "My first bun application",
};

3. Modify src/index.ts.

import appConfig from "config";

console.log(appConfig.message);

4. VSCode intellisense resolve the path well, but when run app bun run ./src it throw error

error: Cannot find package "config" from "/bun-test/src/index.ts"

Bun v1.1.29 (Linux x64)

What problem here? Am i missing some step?
