title: How do I ignore invalid JSON when using json_parse with PrestoDB?
body: <p>I am fairly new to Presto, and am trying to parse a bunch of records containing JSON data. It appears that some of the data is invalid, which causes Presto to abort the query during the call to <code>json_parse</code>. Is it possible to somehow return NULL instead of throwing an error in this case?</p>
  
  <p>It seems like previously you could use <code>try_cast(value as json)</code>, but that was removed in favor of <code>json_parse</code>. Is there any sort of configuration I can change to resolve this, or do I need to resort to creating a custom SerDe?</p>
