[Error] TypeError: Cannot read properties of null (reading 'toString')

[irv-armenta-g]

I will try to add kind of the environment I am working on right now: it's a NextJS project using typescript, NextJS is version 12.3.

Typescript: "typescript": "5.4.5"

tsconfig.json

{
  "compilerOptions": {
    "target": "ES2015",
    "baseUrl": ".",
    "lib": ["dom", "dom.iterable", "esnext"],
    "allowJs": true,
    "skipLibCheck": true,
    "strict": false,
    "forceConsistentCasingInFileNames": true,
    "noEmit": true,
    "incremental": false,
    "esModuleInterop": true,
    "module": "esnext",
    "moduleResolution": "node",
    "resolveJsonModule": true,
    "isolatedModules": true,
    "noUnusedLocals": true,
    "noUnusedParameters": true,
    "jsx": "preserve",
    "paths": {
      "@components/*": ["src/components/*"],
      "@hooks/*": ["src/hooks/*"]
    }
  },
  "include": ["next-env.d.ts", "**/*.ts", "**/*.tsx"],
  "exclude": ["node_modules", "svgo.config.js"]
}

related packages versions: (not full package.json)

{
    "@spidy88/lint-staged-tsc": "^1.0.0",
    "tsc-files": "^1.1.4",
    "husky": "7.0.2",
    "lint-staged": "^15.2.2",
}

I am using babel at the moment to get code test coverage using istanbul ; .babelrc file in root.

{
  "presets": ["next/babel"],
  "env": {
    "development": {
      "plugins": ["istanbul"]
    }
  }
}

And this is the error:

✖ lint-staged-tsc --noEmit --strict:
xxxxxxxxxxx\node_modules\@spidy88\lint-staged-tsc\cli.js:26
const outputLines = stdout.toString().split(/[\r\n]+/);

I'm not able to recreate. No documentation that calls out why stdout would return null for the pipe option. Which platform are you running on? Can you try running tsc-files by itself? I'm curious if that command is failing and causing stdout to return null. Any sort of reproducible minimal environment would be extremely helpful

I am running this on windows.

I updated husky and lint-staged to latest version

  "husky": "9.0.11",
  "lint-staged": "15.2.7",

I still keep getting the same error:

I am not sure what you mean just by running tsc-files by itself? This is a NextJS 13 application.

Tried running lint-staged-tsc on a file:

> yarn lint-staged-tsc -- src/components/SimpleAppear/SimpleAppear.cy.tsx
yarn run v1.22.21
\node_modules\.bin\lint-staged-tsc src/components/SimpleAppear/SimpleAppear.cy.tsx

const outputLines = stdout.toString().split(/[\r\n]+/);

Getting the same const outputLines = stdout.toString().split(/[\r\n]+/); error.
