xml - json text or perl structure exceeds maximum nesting level (max_depth set too low?) -

i getting following error json's encode_json:

json text or perl structure exceeds maximum nesting level (max_depth set low?)

the code in question

my $jsonstring = encode_json($dataxml); 

$dataxml produced xml::simple's xmlin. pointers how remove error?

you error json::pp when structure has 512 levels of nesting. it's meant catch unserializable reference loops (my $data = { }; $data->{foo} = $data;) , prevent malicious attempts use memory.

if aren't problems, if issue need support ginormous structures, can increase threshold using ->max_depth. keep mind that

encode_json($data) 

is short for

my $json = json->new->utf8; $json->encode($data) 

so can use

my $json = json->new->utf8->max_depth(...); $json->encode($data) 

alternatively, json::xs might not have check. if doesn't, installing json::xs avoid error. that's on top of speeding encoding , decoding.
