You really want all that JSON-encoded?</div>
<div><br></div><div>Blessed objects (such as a recordset or a request or a response) typically contain many, many layers that are often going to be overkill when encoding stuff as JSON, when really you just want a few top-level items.</div>
<div><br></div><div>So you should iterate through your objects and/or collections and create a hashref that contains plain primitives (or maybe a few more hashrefs or arrayrefs when needed) instead of asking JSON to translate blessed objects that are dozens of layers deep.</div>
<div><br></div><div>Instead of doing ...->stash( result => [ $rs ] ) build your own data structure, by doing something like</div><div><br></div><div>my $json = {</div><div> data => [],</div><div> count=> $rs->count,</div>
