S3 Adapter fails when "/" is requested

[mabdullahsari]

• Laravel Version: 9.5.1
• PHP Version: 8.1.3
• Database Driver & Version: MySQL 8.0.28

Description:

AwsS3V3Adapter's url method returns an AWS validation error when / is issued as command, because League's PathPrefixer strips it away and ends up with an empty string. GetObject's Key arg requires a string with a length of at least 1, hence the error:

InvalidArgumentException with message 'Found 1 error while validating the input provided for the GetObject operation: [Key] expected string length to be >= 1, but found string length of 0'

Setting the root to / does fix it, but breaks a bunch of other URLs (in my case).

Steps To Reproduce:

Storage::disk('s3')->url('/')

Environment is untouched:

's3' => [
    'driver' => 's3',
    'key' => env('AWS_ACCESS_KEY_ID'),
    'secret' => env('AWS_SECRET_ACCESS_KEY'),
    'region' => env('AWS_DEFAULT_REGION'),
    'bucket' => env('AWS_BUCKET'),
    'url' => env('AWS_URL'),
    'endpoint' => env('AWS_ENDPOINT'),
    'root' => env('AWS_ROOT', ''),
],

I was going to submit a PR to fix this, but I'm not sure if the problem is due to Laravel's adapter or League's prefixer.

Thanks 🙏

Seems like it's a bug in Spatie's Medialibrary package.
