Route [tasks.complete] not defined. (View: /Users/pathparakh/Projects/task/resources/views/tasks/index.blade.php)

This is my TaskController where complete() function is defined to store done_at current time

public function complete($id)
{
    $task = Task::create([
        'done_at' => now(),
    ]);

    return redirect()->route('tasks.index')->withSuccess('Done');
}

This is my web.php route

Route::post('/tasks/complete', 'TaskController@complete');

This is my index page where there is submit button to save current time

<form action="" method="post">
                        @csrf
                        <input type="submit">
                    </form>
