json.errors isn't an array, but an undefined object. You can't use it
like an array and casting it to $A doesn't help either. Since the
errors coming back originally were an array, you'd think this would
work, but it doesn't.
The frustration is that the original code works when json.errors has
values, but doesn't when it's empty.
The code that creates the json:
$json = array('errors' => $fp->getErrors());
$this->sendJson($json);
Any thoughts on how we could evaluate json.errors when it's an empty
representation( "{"errors":[]}")?
