jwt-auth: Can't get token with Laravel 6.0 and jwt-auth 1.0.0-rc.5 when trying to authenticate

Token value is always false

Hello. I used jwt-auth 1.0.0-rc.5 to handle authentication with laravel 6.0. My AuthController code is pasted below.

When registering a new user with the method register in AuthController, I succesfully get a jwt token.

But when trying to athenticate the user I created earlier, token value is always false

`<?php

namespace App\Http\Controllers;

use DB; use Hash; use App\User; use App\RoleUser; use Illuminate\Http\Request;

class AuthController extends Controller { public function authenticate(Request $request) { $credentials = $request->only(‘email’, ‘password’);

	$token = auth()->attempt($credentials);

    // var_dump(Hash::make($credentials['password']));
    // var_dump($token);
    
	if($token)
		return $token;
	return response()->json(['error' => 'Unauthorized'], 401);
}

public function register(Request $request)
{

    $request->validate([
        'role'      =>  'required',
        'email'     =>  'required|unique:users',
        'password'  =>  'required',
        'firstname' =>  'required',
        'lastname'  =>  'required'
    ],[
        'role'          => 'Le niveau de role est requis',
        'email.unique'  => "L'adresse email est requise",
        'password'      => 'Le mot de passe est requis',
        'firstname'     => 'Le prénom est requis',
        'lastname'      => 'Le nom de famille est requis'
    ]);

    DB::beginTransaction();

        $user = User::create([
         'email'        => $request->email,
         'password'     => $request->password,
         'firstname'    => $request->firstname,
         'lastname'     => $request->lastname
        ]);

        RoleUser::create([
            'role_name' => $request->role,
            'user_id'  => $user->id
        ]);

    DB::commit();

    $token = auth()->login($user);

    // var_dump($token);

    return $this->respondWithToken($token);
}

 protected function respondWithToken($token)
{
    return response()->json([
        'access_token' => $token,
        'token_type'   => 'bearer',
        'expires_in'   => auth()->factory()->getTTL() * 60
    ]);
}

} `
