}

Steps to reproduce

1. Set up a Vue 3 project using the above package.json dependencies.
2. Add a tsconfig.app.json file:

{
  "extends": "@vue/tsconfig/tsconfig.dom.json",
  "include": ["env.d.ts", "src/**/*", "src/**/*.vue"],
  "exclude": ["src/**/__tests__/*"],
  "compilerOptions": {
    "composite": false,
    "baseUrl": ".",
    "paths": {
      "@/*": ["./src/*"]
    }
  }
}

3. Run the type-checking script:

vue-tsc --noEmit -p tsconfig.app.json --composite false

What is expected?

vue-tsc completes type-checking successfully without errors.

What is actually happening?

/home/wanjala/WebstormProjects/stephenWanjala.github/node_modules/vue-tsc/index.js:34
throw err;
^
Search string not found: "/supportedTSExtensions = .*(?=;)/"
Node.js v23.1.0

Any additional comments?

Replacing the vue-tsc with tsc works fine or using a typescript version before the latest version 5.7.2 works
