title: Template error Type 'AbstractControl' is not assignable to type 'FormControl'
body: <p>Why am I getting this error?</p>
  <p>The following code works in another application</p>
  <pre><code>          &lt;input class=&quot;form-control form-control-sm&quot; type=&quot;number&quot; min=&quot;0&quot;
              [formControl]='invoiceForm.get(&quot;quantity&quot;)'&gt;
  </code></pre>
  <p>in this new application it works too but still complaining in the terminal</p>
  <pre><code>  Type 'AbstractControl' is not assignable to type 'FormControl'.
  </code></pre>
