Perl Decode JSON - Not an ARRAY referencce - json

Question

Getting error "Not an ARRAY reference" when trying to print my hash. Not sure where I am going wrong. IS there a way to print the decoded json in such a way that it makes identfying the hash elements easier?
use JSON qw( decode_json );
my $owm_json= <<'__EOI__';

my $decoded = decode_json($owm_json);
print $decoded->{list}[0]->{weather}[0]->{description};

Answer 1

Your string $owm_json isn't a valid Perl string. From the short segment:
"{"cod":"200","city":{"id":"4270936","name":
This should actually be:
"{\"cod\":\"200\",\"city\":{\"id\":\"4270936\",\"name\":
You need to escape the inner quotation marks. Try putting use strict at the beginning of the script and that should have caught this error.
Update from comments:
Looking at your JSON data, you do have an incorrect access to the descpiption field. Here's the section you are trying to display in your example:
"list" : {
"0" : {
"weather" : [{
"id" : 803,
"main" : "Clouds",
"description" : "broken clouds",
"icon" : "04n"
}
],
Notice that after "list" you have "0", not an array reference which would use the [] characters. In your script, after {list} use {0} and not [0] and that should fix your issue:
print $decoded->{list}{0}{weather}[0]{description};

Answer 2

The value of list is a hash (...,"list":{"0":{...},...), but you try to dereference is with ->[0] which is an array dereference.
You want:
$decoded->{list}{0}{weather}[0]{description}
instead of
$decoded->{list}[0]{weather}[0]{description}
