Crash in unicorn/no-instanceof-builtins and similar rules when linting .vue files #2643
Description
After upgrading from eslint-plugin-unicorn@56.0.1 to 57.0.0+ I'm experiencing ESLint crashes when linting .vue files with the following error:
Stack Trace
ESLint: 9.26.0
TypeError: Cannot read properties of null (reading 'childScopes')
Occurred while linting ./src/App.vue:14
Rule: "unicorn/explicit-length-check"

- unicorn/no-instanceof-builtins
- unicorn/number-literal-case
- unicorn/prefer-array-some
- unicorn/prefer-includes
Minimal package.json to reproduce:
{
"name": "test_eslint",
"packageManager": "yarn@4.6.0",
"devDependencies": {
"eslint": "^9.26.0",
"eslint-plugin-unicorn": "^59.0.0",
"eslint-plugin-vue": "^10.1.0",
"vue-eslint-parser": "^10.1.3"
}
}and eslint.config.mjs
import unicorn from "eslint-plugin-unicorn";
import vue from "eslint-plugin-vue";
export default [
unicorn.configs["flat/recommended"],
...vue.configs["flat/recommended"],
{
files: ["**/*.vue"],
rules: {
// skipping the following rules fixes the issue
// "unicorn/no-instanceof-builtins": "off",
// "unicorn/number-literal-case": "off",
// "unicorn/prefer-array-some": "off",
// "unicorn/prefer-includes": "off"
}
}
];I'm able to work around the issue by disabling the above rules for *.vue files, but I'd like to keep them enabled to ensure consistent linting behavior across all files, including Vue SFCs.
