Are you using Telescope? Is this the problem you're experiencing? laravel/telescope#347

[ClaudioVarandas]

yes, im using Telescope. Tx!

[mateusgalasso]

I've runned

php artisan clear
php artisan config:clear

Solved for me

[nakov0301]

For someone still having the issue, it can be solved adding

<server name="TELESCOPE_ENABLED" value="false"/> in phpunit.xml.

[nezaboravi]

Put it together:

<server name="TELESCOPE_ENABLED" value="false"/>
php artisan optimize

I'm not using telescope package, but i've received the same exception on every php artisan call.
I didn't understand what code block crashes.
Over internet there are many resolutions with cache cleaning. Those users received the same message while running phpunit command.
I've tried to run phpunit and received an error related to configuration of one of packages that i've used. So I fixed package config problem and phpunit command runs well. Also, php artisan runs OK for now.
Hope my solution will be useful to someone.

I had the same problem after upgrading with composer update. I had to downgrade. Nothing above worked for me.

Some problem after upgrading from 6 to 7 version

[ProteanCode]

Lumen, upgrading from

• Updating laravel/framework (v8.14.0 => v8.18.1): Downloading (100%)
• Updating laravel/lumen-framework (v8.2.0 => v8.2.1): Downloading (100%)

Happened during seeding
User::factory()->count(200)->create();

Actually a simple
$factory = User::factory();
was enough to make that error

Workaround:

$factory = \Database\Factories\UserFactory::new();
$factory->count(200)->create();

If you are upgrading to Laravel 6, the problem may be in the missing str_slug() function in configs, replace it with Str:slug()

[abinrimal]

For someone still having the issue, it can be solved adding

<server name="TELESCOPE_ENABLED" value="false"/> in phpunit.xml.

Where can we find this, I don't have phpunit.xml file anywhere in my files.

[athamidn]

put dd($exception); in App\Exceptions\Handler::report()
It gives you a better error message.
there was an error in filesystem config for me!

@athamidn Super star, thanks! This was tripping me up too; was referencing a constant in my config files defined in a database seeder (which had changed to being namespace in a laravel 8 update).
