After installation strictly according to the instructions, I have a exception:

Unresolvable dependency resolving [Parameter #0 [ $app ]] in class Codecasts\Auth\JWT\Auth\Guard in Container.php (line 910)

Laravel 5.4.28

I did:

1. composer require codecasts/laravel-jwt
2. added service provider Codecasts\Auth\JWT\ServiceProvider::class
3. published vendor files
4. generated and added secret to .env
5. changed driver in api guards to 'jwt'
