Laravel AWS S3 Error

I'm thinking I installed this wrong, but keep getting the same error. Installed league/flysystem-aws-s3-v3. S3 creds are setup in .env file.

Added these to the require in composer.

"aws/aws-sdk-php"
"aws/aws-sdk-php-laravel": "~3.0"
--------------------------------------------

Code:

$s3 = \Storage::disk('s3');
$s3->put($location, file_get_contents($image), 'public');

Getting the following error:

exception 'InvalidArgumentException' with message 'Missing required client configuration options: 

' in /var/www/laravel/vendor/aws/aws-sdk-php/src/ClientResolver.php:328

Did some research online and couldn't find a solution.
