title: Field 'fullname' doesn't have a default value (SQL: insert into `contacts` (`updated_at`, `created_at`)
body: <p>I get the following error on Laravel 5.6. But the values I send are not null. I'm running MySQL in Docker on my local. When I destroy the container and create a new mysql container it works fine for a while. I think this is a RAM error.</p>
  <p>that is my macbook:</p>
