Can not get access to Telescope dashboard - laravel

Question

I want to add telescope into my laravel 8 app, but having in .env
APP_ENV=local
TELESCOPE_ENABLED=true
and reading at site :
https://laravel.com/docs/8.x/telescope
The Telescope dashboard may be accessed at the /telescope route. By default, you will only be able to access this dashboard in the local environment.
on url
http://local-tads.com/telescope
I got 404 error, where http://local-tads.com - is local hosting of my app
In app/Providers/AppServiceProvider.php file I added lines :
<?php
namespace App\Providers;
class AppServiceProvider extends ServiceProvider
...
if ($this->app->environment('local')) {
$this->app->register(\Laravel\Telescope\TelescopeServiceProvider::class);
\Event::listen(
[
TransactionBeginning::class,
],
function ($event) {
...
I have unmodified vendor/laravel/telescope/config/telescope.php file.
Have I to add route in routes/web.php and in which way ?
How to get access to telescope dashboard ?
UPDATED BLOCK :
I run both commands :
php artisan telescope:install
php artisan migrate
But I did not find config/telescope.php, so I copied it from /vendor/ subdirectory
Running command
php artisan route:list
has no any “telescope” entry.
In file app/Providers/AppServiceProvider.php I added lines with telescope :
<?php
namespace App\Providers;
use App\Library\Services\AdminCategoryCrud;
//use App\Providers\TelescopeServiceProvider;
use Illuminate\Database\Events\TransactionBeginning;
use Illuminate\Database\Events\TransactionCommitted;
use Illuminate\Database\Events\TransactionRolledBack;
use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\Blade;
use Laravel\Telescope\IncomingEntry;
use Laravel\Telescope\Telescope;
use Laravel\Telescope\TelescopeServiceProvider;
class AppServiceProvider extends ServiceProvider
{
public function register()
{
if ($this->app->environment('local')) {
$this->app->register(\Laravel\Telescope\TelescopeServiceProvider::class);
$this->app->register(TelescopeServiceProvider::class);
}
Not sure if all is correct?
in env I have :
APP_ENV=local
TELESCOPE_ENABLED=true
and in composer.json I added line :
"extra": {
"laravel": {
"dont-discover": [
"laravel/telescope"
]
}
},
and updated composer
But http://local-tads.com/telescope - still raise 404 error...
Thanks in advance!

Answer 1

I have this problem but I attention Laravel Documentation I watch this code and run them:
telescope:install
, you should remove the
TelescopeServiceProvider
service provider registration from your application's
config/app.php
configuration file. Instead, manually register Telescope's service providers in the
register
method of your
App\Providers\AppServiceProvider
class.

Answer 2

A potential answer to your problem could be removing the telescope package from the dont-discover array. So your new extra section would be like this one:
"extra": {
"laravel": {
"dont-discover": []
}
}
Also, don't forget to dump your autoload by running composer dump-autoload in your project folder. I hope this helps you :D
