Erro ao utilizar o Token para visualizar os episódios

Olá, Lucio. Preciso de mais detalhes sobre sua implementação.

Aparentemente o token que você recebeu foi alterado antes de enviar de volta pra API.

TokenController

namespace App\Http\Controllers;

use App\User;
use Firebase\JWT\JWT;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Hash;

class TokenController extends Controller
{
    public function gerarToken(Request $request)
    {
        $this->validate($request, [
            'email' => 'required|email',
            'password' => 'required'
        ]);
        $usuario = User::where('email', $request->email)->first();


        if (is_null($usuario) || !Hash::check($request->password, $usuario->password)) {
            return response()->json('Usuário ou senha inválidos', 401);
        }

        $token = JWT::encode(['email' => $request->email], env('JWT_KEY'));

        return [
            'access_token' => $token
        ];
    }
}

UsuarioSeeder

use Illuminate\Database\Seeder;
use App\User;
use Illuminate\Support\Facades\Hash;

class UsuarioSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        User::create([
            'email'=> 'teste@email',
            'password'=> Hash::make('senha')
        ]);
    }
}

DatabaseSeeder

use Illuminate\Database\Seeder;

class DatabaseSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        $this->call('UsuarioSeeder');
    }
}

User

namespace App;

use Illuminate\Auth\Authenticatable;
use Illuminate\Contracts\Auth\Access\Authorizable as AuthorizableContract;
use Illuminate\Contracts\Auth\Authenticatable as AuthenticatableContract;
use Illuminate\Database\Eloquent\Model;
use Laravel\Lumen\Auth\Authorizable;

class User extends Model implements AuthenticatableContract, AuthorizableContract
{
    use Authenticatable, Authorizable;
    protected $table = 'usuarios'; 

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'email',
    ];

    /**
     * The attributes excluded from the model's JSON form.
     *
     * @var array
     */
    protected $hidden = [
        'password',
    ];
}

CriarTabelaUsuarios

namespace App;

use Illuminate\Auth\Authenticatable;
use Illuminate\Contracts\Auth\Access\Authorizable as AuthorizableContract;
use Illuminate\Contracts\Auth\Authenticatable as AuthenticatableContract;
use Illuminate\Database\Eloquent\Model;
use Laravel\Lumen\Auth\Authorizable;

class User extends Model implements AuthenticatableContract, AuthorizableContract
{
    use Authenticatable, Authorizable;
    protected $table = 'usuarios'; 

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'email',
    ];

    /**
     * The attributes excluded from the model's JSON form.
     *
     * @var array
     */
    protected $hidden = [
        'password',
    ];
}

Acho que o problema é o arquivo JWT.

Como você está enviando de volta o token pras requisições seguintes? Faltou essa parte
