Class 'League\Flysystem\AwsS3v3\AwsS3Adapter' not found (Laravel + Heroku)

you forgot to install the required library

composer require league/flysystem-aws-s3-v3

good luck

For laravel 8 use

 composer require --with-all-dependencies league/flysystem-aws-s3-v3 "^1.0"

@localheinz When I did the deploy I run: composer install

But in heroku the packages install them from the console that has the heroku dashboard.

But when I want to add or remove the package league/flysystem-aws-s3-v3 the following message comes out:

Package listed for update is not installed. Ignoring.

So I think there's a cache in between, because everything works fine for me.
