Where can I log & debug Velocity Template Language (VTL) in AWS AppSync? : <ol>
<li><p>Is there any easy way to log or debug VTL coming from Request Mapping Template &amp; Response Mapping Template rather than sending <strong>Queries</strong> &amp; <strong>Mutations</strong> to debug &amp; log?</p></li>
<li><p>Also, is there any Playground to check &amp; play with VTL just like we can do with JavaScript in Web Console?</p></li>
<li><p>Can we work with AWS AppSync offline &amp; check if everything written in VTL works as expected? </p></li>
</ol>
