title: ERROR: services.db Additional property volume is not allowed
body: <p>#solved
  there a typo on volume , it must be volumes</p>
  <p>i want to ask a question, i already created the <code>Dockerfile</code> and also <code>docker-compose.yaml</code> in my laravel tutor project, and i faced this problem after wrote all the code in the <code>docker-compose.yaml</code> in the terminal</p>
  <p>im running <code>docker-compose up</code> in the terminal and it shows the <code>services.db Additional property volume is not allowed</code>. what should i do to solve this error. i am sorry this is my first time using docker.</p>
  <pre><code>version: &quot;3.7&quot;
