title: Error: Cannot determine GraphQL input type when passing array as input type in typegraphql
body: <p>I'm using TypeGraphQL and TypeORM. In my input types, I have a field that looks like this:</p>
  
  <pre class="lang-js prettyprint-override"><code>@Field(() =&gt; [String], { nullable: true })
    options: string[];
  </code></pre>
  
  <p>However. I keep getting this error, </p>
  
  <pre><code>Error: Cannot determine GraphQL input type for options
  </code></pre>
  
  <p>How do I solve this?</p>
