title: laravel Closed without sending a request; it was probably just an unused speculative preconnection
body: <p>i'm new to laravel/lumen framework, following this article: <a href="https://omojolasamsonade.medium.com/laravel-8-how-to-create-restful-apis-with-lumen-8-8859960bfac8" rel="nofollow noreferrer">https://omojolasamsonade.medium.com/laravel-8-how-to-create-restful-apis-with-lumen-8-8859960bfac8</a>
  i'm trying to set up a rest api server.
  i can connect to database and retrieve users and single user information. the problem is i can't create an user, i have this error:</p>
  <pre><code>SQLSTATE[42S22]: Column not found: 1054 Unknown column 'updated_at' in 'field list' (SQL: insert into `users` (`name`, `email`, `updated_at`, `created_at`) values (john, john@john.com, 2021-01-29 14:34:42, 2021-01-29 14:34:42))
  </code></pre>
  <p>and in the server console i have</p>
  <pre><code>[Fri Jan 29 15:34:42 2021] [::1]:5100 Accepted
  [Fri Jan 29 15:34:42 2021] [::1]:5101 Accepted
  [Fri Jan 29 15:34:42 2021] [::1]:5100 Closed without sending a request; it was probably just an unused speculative preconnection
  [Fri Jan 29 15:34:42 2021] [::1]:5100 Closing
  [Fri Jan 29 15:34:43 2021] [::1]:5101 [500]: POST /api/v1/users/add
  [Fri Jan 29 15:34:43 2021] [::1]:5101 Closing
  </code></pre>
  <p>BUT in the user model i didn't define the <code>updated_at</code>, <code>created_at</code> fields, just name and email, neither i have them in db, i think laravel adds automatically these fields.
  someone could help me? thanks</p>
