Since upgrading my application from Laravel 7 to 8, I've been having some minor issues with Laravel Passport. I created a test feature to retrieve a Passport token to make sure it was working, but I can't get it back. When I call passport.token I always get the same message:

array:3 [

  "error" => "invalid_client"

  "error_description" => "Client authentication failed"

  "message" => "Client authentication failed"

]

I have tried several things, but here is my current code:

use Illuminate\Support\Str;

use Laravel\Passport\Client as OauthClient;

use Modules\Sapiendo\Tests\SapiendoTestCase;



/** @test */

    public function we_can_authenticate_and_use_api_endpoints_with_client_credential_grant_token()

    {

        $customer = $this->createFullCustomer();



        /** @var OauthClient $oauthClient */

        $oauthClient = OauthClient::create([

            'user_id' => null,

            'name' => 'ClientCredentials Grant Client',

            'secret' => Str::random(40),

            'redirect' => 'http://localhost',

            'personal_access_client' => false,

            'password_client' => false,

            'revoked' => false,

        ]);

        $state = Str::random(40);

        $autorization = $this->get(route('passport.authorizations.authorize', [

            'client_id' => $oauthClient->id,

            'redirect_uri' => 'http://localhost',

            'response_type' => 'code',

            'scope' => '',

            'state' => $state,

        ]));

        $autorization->assertStatus(302);

        // D'abord on demande un token avec les identifiants créés

        $tokenRequest = $this->post(route('passport.token'), [

            'grant_type' => 'client_credentials',

            'client_id' => $oauthClient->getKey(),

            'client_secret' => $oauthClient->secret,

            'code' => $state,

        ]);

            //->assertSuccessful();

        dd($tokenRequest->json());

    ...

Before this update I didn't have to go through the passport.authorizations.authorize route to get the code, I could go directly to the passport.token step
