Laravel route returning "No response data for this request" when accessing an image file

I'm working on a Laravel application where I need to serve images stored in the filesystem and display them on a web page. I have defined the following route in web.php:

Route::post('/image/{campaign}/{folder}/{filename}', function ($campaign, $folder, $filename) {
    $path = "private/campaigns-images/campaign-$campaign/$folder/$filename";

    if (!Storage::exists($path)) {
        abort(404);
    }

    $file = Storage::get($path);
    $mimeType = Storage::mimeType($path);
    
    return Response::make($file, 200)->header("Content-Type", $mimeType);
})->name('image.show');

HTML and JavaScript In my frontend, I'm trying to load and set the image as a background for a Fabric.js canvas using JavaScript:

<div class="mySlides">
    <div class="numbertext">1 / 3</div>
    <img id="background-image" 
        src="{{ route('image.show', ['campaign' => 1, 'folder' => 'images_17', 'filename' => 'DJI_20241105104710_0123_V.JPG']) }}"
        alt="Campaign Image"
        style="width: 100%; max-width: 1200px; height: auto;">
</div>

<canvas id="canvas"></canvas>

const canvas = new fabric.Canvas('canvas');

function setBackgroundImage() {
    const imgElement = document.getElementById('background-image'); 

    if (imgElement) {
        imgElement.onload = function () {
            fabric.Image.fromURL(imgElement.src, function (img) {
                canvas.setBackgroundImage(img, canvas.renderAll.bind(canvas), {
                    scaleX: canvas.width / img.width,
                    scaleY: canvas.height / img.height
                });
            });
        };

        // If the image is already loaded (from cache), trigger onload manually
        if (imgElement.complete) {
            imgElement.onload();
        }
    }
}
window.onload = function () {
    setBackgroundImage();
};

Issue

When I try to access an image via (GET request): http://127.0.0.1:8000/admin/image/1/images_17/DJI_20241105104710_0123_V.JPG I get the response "No response data for this request" but if I click on the same link the resource is available

What I've Tried Checked that the file exists using Storage::exists($path), and it does. Changed the route method from POST to GET, but still no response. Checked storage/logs/laravel.log but no related errors appear. Tried return response('Test Response'); inside the route, but nothing is displayed..
