Feature test "No adapter for resource type: "

Hi everybody.

I'm new in L8 and I'm trying to write feature tests for API connection to my model under sanctum middleware.

This is an extract of my routes/api.php:

Route::middleware(['auth:sanctum'])->group(function () {
    JsonApi::register('default')->withNamespace('\App\Http\Controllers\Api')->routes(function ($api) {
        // it work's
        Route::get('timetracks/per-day', 'TimetracksController@perDay')->name('timetracks-per-day');
        // it doesn't work
        $api->resource('timetracks');
        // other routes ...
    });
});

This is my test:

public function testTimetrackAccess()
{
    $worker = Worker::factory(1)->active()->create()->first();
    $response = $this->post(route('api:v1:login'), ['badge' => $worker->badge]);
    $response->assertStatus(200);

    $response = $this->actingAs($worker)->get(route('api:v1:user'));
    $response->assertStatus(200);

    $response = $this->actingAs($worker)->get(route('api:v1:timetracks-per-day'));
    $response->assertStatus(200);

    $response = $this->actingAs($worker)->get(route('api:v1:timetracks.index'));
    $response->assertStatus(200);
}

But when I run it, the last assertion fails with this 500 error: "No adapter for resource type: ". All works fine when I call all routes with Postman.

Is there something wrong or forgotten?

Thank's a lot.
