404 not found when using laravel filemanager package

I have no problem using the filemanager.

This means that when I create a post, for example an article with a photo, I do it without any problem.

But when I try to edit the post, the part where I put the standalone Button can not load the file manager and gives a 404 error

Maybe my main problem is in the route part that I did not fully understand

web.php code

Route::group(['prefix' => 'laravel-filemanager', 'middleware' => ['web', 'auth:admin']], function () {
    \UniSharp\LaravelFilemanager\Lfm::routes();
});

Route::get('/admin/category/edit/{category}', [CategoryController::class, 'edit'])
    ->name('edit.category')
    ->middleware('auth:admin');

//update
Route::put('/admin/category/edit/{category}', [CategoryController::class, 'update'])
    ->name('update.category');

this is create_category.blade.php

Solution

What version of Laravel and package do you use?

If you are using version laravel 8, install this version of the package:

"unisharp/laravel-filemanager": "v2.2.0"
