Laravel routing to a js script on my server and load that to page

I would like to route a request that looks like this:
https://sub.domain.nl/tracking/MM-123/tracker.js

To my javascript in this directory:
Resources/js/Scrips/tracking/tracker.js

However, it looks like the server/laravel is looking for this script:
https://sub.domain.nl/tracking/MM-123/tracker.js

In the /public folder.

However, I want it load it just like a normal view / page from the server.

My web.php router:

Route::group([], function () {
  Route::get('/tracking/{script}/tracker.js', [TrackingScriptController::class, 'index'])->name('tracking');
});

My TrackingScriptController.php:

<?php

namespace AppHttpControllers;

use IlluminateHttpRequest;
use IlluminateSupportFacadesResponse;
use IlluminateSupportFacadesFile;

class TrackingScriptController extends Controller
{
    public function index($script)
    {
        // Construct the path to the script file
        $filePath = resource_path("js/Scripts/Tracking/tracker.js");

        // Check if the file exists
        if (!File::exists($filePath)) {
            // You can return a 404 or some other error if the file is not found
            abort(404, 'Script not found');
        }

        // Read the contents of the file
        $scriptContents = File::get($filePath);

        // Return the contents with the correct Content-Type header
        return Response::make($scriptContents, 200, ['Content-Type' => 'application/javascript']);
    }
}

?>

But the browser keeps giving 404 page not found, in console:

Failed to load resource: the server responded with a status of 404 () tracker.js

So it looks like my laravel app is trying to look for this .js file inside of the public app. When I remove .js from the URL like this:
https://sub.domain.nl/tracking/MM-123/tracker

And my web.php to this:

Route::group([], function () {
  Route::get('/tracking/{script}/tracker.', [TrackingScriptController::class, 'index'])->name('tracking');
});

It works fine.

I’m using Laravel (Breeze starter kit) + Inertia + Vue.

Does anyone have an idea how to fix this? I have no idea unfortunately after trying a lot of different things.
