title: Trying to store POINT geometry using Laravel Backpack
body: <p>I'm using Backpack to display CRUD for various MYSQL database tables.
  One of the tables contains a POINT type.</p>
  <p>I am using the
  Grimzy package to to handle the POINT elsewhere like so:</p>
  <pre><code>   // Convert point from JSON coordinates to a MYSQL Point
  $pnt = new Point($input['MonitoringPointGISLocation']['coordinates'][1],
                   $input['MonitoringPointGISLocation']['coordinates'][0]);
  
  $input['MonitoringPointGISLocation'] = $pnt;
  </code></pre>
  <p>The CRUD controller contains</p>
  <pre><code>CRUD::column('MonitoringPointGISLocation')-&gt;label('GIS Location');
  </code></pre>
  <p>when I run an update I get the following error</p>
  <p><img src="https://i.stack.imgur.com/ElxCo.png" alt="Error for Backpack CRUD" /></p>
  <p>What is the correct formulation to save a POINT to the database with Backpack?</p>
