Key "plugins": Cannot redefine plugin "unicorn"

[rafipiccolo]

I'm transitionning from eslint 8 to 9.

in eslint 9 there is not one rule in particular that fails. I just cant run eslint

.eslintrc

{
    "plugins": ["unicorn"],
    "extends": [ "eslint:recommended", "plugin:unicorn/recommended" ] 
    "parser": "@babel/eslint-parser",
    "parserOptions": {
        "ecmaVersion": "latest",
        "sourceType": "module",
        "requireConfigFile": false
    }
}

to
eslint.config.js

import js from "@eslint/js";
import unicorn from "eslint-plugin-unicorn";

export default [
    // activate this line to get error
    // before it was named : "eslint:recommended"
    // --------
    // js.configs.recommended, 

    unicorn.configs['flat/recommended'],
    {
        files: ["**/*.js"],
        languageOptions: {
            parser: babelParser,
            parserOptions: {
                ecmaVersion: "latest",
                sourceType: "module",
                requireConfigFile: false,
            },
        },
        plugins: {
            unicorn,
        }
    }
}

eslint server.js 

Oops! Something went wrong! :(

i tried setting

[rafipiccolo]

ok my bad, i needed to remove this part

plugins: {
            unicorn,
        }

I guess the extends now does it itself

unicorn.configs['flat/recommended'] enables "unicorn" plugin
