Repro Code

ESLintUtils.getParserServices(context, true).program.getSourceFile('/Users/user/Documents/repo/src/context.ts');

ESLint Config

module.exports = {
  parser: "@typescript-eslint/parser",
  parserOptions: {
    project: "./tsconfig.json",
  },
  plugins: ["@typescript-eslint", "import-access"],
  extends: ["eslint:recommended", "plugin:@typescript-eslint/recommended"],
  ignorePatterns: [".eslintrc.js", "node_modules"],
  rules: {
    "import-access/no-imports-outside-package": [
      "error",
      {
        strictMode: true,
      },
    ],
  },
};

tsconfig

{
  "compilerOptions": {
    "plugins": [
      {
        "name": "eslint-plugin-import-access",
        "strictMode": true
      }
    ],
    "target": "ES2017",
    "module": "CommonJS",
    "esModuleInterop": true,
    "noEmit": true
  },
  "include": ["./src/**/*"]
}

Expected Result

program.getSourceFile('...') returns requested file when parserOptions.project is specified in .eslintrc, but when parserOptions.project is missing, getSourceFile('...') returns the file that is being linted. I would like to remove this setting from .eslintrc, but I can't as it breaks my plugin.

Actual Result

the wrong file is returned

Additional Info

Provided configs are the configs of the project using the plugin, not the project that compiles the plugin
