laravel service-provider closure binding PHP

I'm trying to debug After trying multiple solutions online, I still can't figure this out. I'm updating my dependencies and I'm sure I'm missing something obvious here, but Quick question that's been bugging me - I am currently working with an scenario with a custom service provider in Laravel 9 where I'm trying to bind a closure to the service container..... The closure is intended to access certain properties from the service provider class, but it seems to be losing its context, resulting in a `BindingResolutionException`. Here is a simplified version of what I have: ```php namespace App\Providers; use Illuminate\Support\ServiceProvider; class CustomServiceProvider extends ServiceProvider { protected $someProperty = 'Hello World'; public function register() { $this->app->singleton('customService', function () { return new CustomService($this->someProperty); }); } } ``` When I attempt to resolve `customService`, I get the following behavior: ``` BindingResolutionException: Target class [customService] does not exist. ``` I have tried using `use ($this)` in the closure, but that gives me a `want to bind an instance of object as a singleton` behavior. I've also looked into using `bind` instead of `singleton`, but I need a single instance throughout the application. Interestingly, if I replace `CustomService($this->someProperty)` with a hardcoded string like `CustomService('Hello World')`, it works fine. Can anyone guide to understand why the closure loses the reference to `$this` in this context and how I can correctly bind the closure to retain access to the class properties? For context: I'm using Php on Windows. Has anyone else encountered this? This is part of a larger service I'm building. How would you solve this? I recently upgraded to Php 3.10. Could this be a known issue? The stack includes Php and several other technologies. Any advice would be much appreciated. This is for a microservice running on Linux.
