Thank you for upgrading this awesome boilerplate starter for Slim 4: Some issues I noticed FYI only.

2.
package.json

npm{
"name": "slim4",
"version": "1.1.0",
"description": "Slim4 boilerplate",
"main": "webpack.mix.js",
"scripts": {
"dev": "node node_modules/cross-env/dist/bin/cross-env.js NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --config=node_modules/laravel-mix/setup/webpack.config.js",
"watch": "node node_modules/cross-env/dist/bin/cross-env.js NODE_ENV=development node_modules/webpack/bin/webpack.js --watch --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
"watch-poll": "node node_modules/cross-env/dist/bin/cross-env.js NODE_ENV=development node_modules/webpack/bin/webpack.js --watch --watch-poll --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
"hot": "node node_modules/cross-env/dist/bin/cross-env.js NODE_ENV=development node_modules/webpack-dev-server/bin/webpack-dev-server.js --inline --hot --config=node_modules/laravel-mix/setup/webpack.config.js",
"prod": "node node_modules/cross-env/dist/bin/cross-env.js NODE_ENV=production node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"
},

a) I removed npm at top left as complaint about json not being able to run in multiple levels
b) I removed --hide modules as complaint when I ran npm run dev
c) I updated the dependencies as mix would not compile when I used npm run dev.
Below worked.
"homepage": "https://github.com/FernandoCalmet",
"devDependencies": {
"cross-env": "^5.2.1",
"laravel-mix": "^6.0.49",
"resolve-url-loader": "^5.0.0",
"sass": "^1.19.0",
"sass-loader": "^14.1.0",
"vue-template-compiler": "^2.7.16"
}
}
I.e. laravel mix came back compiled successfully when I ran npm run dev.

3. I initially removed captcha as I struggled to get it configured. I noticed that when I tried to register a new user it failed.
   I needed to comment out captcha on the registration form.
   Also commented out // 'g-recaptcha-response'=> 'required|recaptcha' in the AuthController.
   This done I could register a new user.
   I will replace captcha when I figure out how it works.
   I must confess that I have never used a captcha before so new to me.

I have an issue with the Database/Migrations/MigrationsStub.php?
In PHPStorm it is complaining with a red line from app/Databse/Migrations/MigrationStub.php. Not sure why. But program is working regardless.

Thank you for upgrading the boiler plate to work on php version 8+. Awesome!
