sourceCode undefined in every rule

[Silon]

I created package with own rules where I use stylistic with next/recommended

// eslin-plugin-test/index.js

module.exports = {
  configs: {
    nextjs: {
      plugins: ["@stylistic"],
      extends: ["plugin:@next/next/recommended"],
      rules: {
        "@stylistic/max-len": ["error", 120],
      },
    },
  },
};

Then I use it in my NextJS project

//  nextproject/.eslintrc.js

/** @type {import('eslint').Linter.Config} */
module.exports = {
  root: true,
  extends: ['plugin:@test/test/nextjs'],
  parserOptions: {
    project: './tsconfig.json',
    ecmaVersion: 'latest',
  },
  env: {
    es6: true,
    node: true,
  },
};

The problem is that every rule added into rules in index.js file causes an error:

[Error - 18:41:35] TypeError: Cannot read properties of undefined (reading 'lines')
Occurred while linting /Users/silon/Developer/nextjs-template/.eslintrc.js:2
Rule: "@stylistic/max-len"
    at checkProgramForMaxLength

The problem in this case is in max-len.js file in this line:

function checkProgramForMaxLength(node) {
  // split (honors line-ending)
  const lines = sourceCode.lines;

When I remove max-len rule from index.js eslint works good

Hi @Silon.
I think you need to use ESLint v8.40 or newer.
New those properties were added in v8.40.

@ota-meshi you're right! In my library I got newest but project had old version. Thank you
