尝试访问JSON数组的内容时出错.

这是我的JSON数组assets.json的内容:

[{"id":1002,"interfaces":[{"ip_addresses":[{"value":"172.16.77.239"}]}]},{"id":1003,"interfaces":[{"ip_addresses":[{"value":"192.168.0.2"}]}]}]

这是我的代码

#!/usr/bin/perl

use strict;
use warnings;
use JSON::XS;
use File::Slurp;

my $json_source = "assets.json";   

my $json = read_file( $json_source ) ;
my $json_array = decode_json $json;

foreach my $item( @$json_array ) { 
    print $item->{id};
        print "\n";
    print $item->{interfaces}->{ip_addresses}->{value};
        print "\n\n";
}

我得到$ item - > {id}的预期输出但是当访问嵌套元素时,我收到错误"Not a HASH reference"
