Laravel Driver错误 - 不支持Driver []

Anyone else had this issue:

I set my filesystems.php config defualt from local to cloud (which is set to my s3) and I get this error with my storage code:

$path = $request->file('avatar')->store('avatars'); -> in my UserController

Error : Driver [] is not supported.

If I leave the filesystems config to stock and just run this code the image uploads to my s3 fine

$path = $request->file('avatar')->store('avatars', 's3'); -> in my UserController

shouldnt $path = $request->file('avatar')->store('avatars'); run to what ever the default is without passing the specific driver? I tried 'default' => 's3', and that gets the same error

CONFIG DRIVERS

'default' => 'local',
'cloud' => 's3',
'disks' => [

        'local' => [
            'driver' => 'local',
            'root' => storage_path('app'),
        ],

        'public' => [
            'driver' => 'local',
            'root' => storage_path('app/public'),
            'url' => env('APP_URL').'/storage',
            'visibility' => 'public',
        ],

        's3' => [
            'driver' => 's3',
            'key' => env('AWS_KEY'),
            'secret' => env('AWS_SECRET'),
            'region' => env('AWS_REGION'),
            'bucket' => env('AWS_BUCKET'),
        ],

    ],

I guess, that whether your example with manually typing a storage to the store() function works well, you can have a problem with storage config. Could you, please, show your configuration file with storage types?
