No such pseudo-hash field
This is the error you typically get when you incorrectly access an array as a hash, and have an old Perl that still does support pseudo hashes (such as 5.8.x).
In your specific case, your $license->{'properties'} is an arrayref, but you treat it as a hashref.
Something like this should work better
my $maxEngine;
my $props = $license->{'properties'};
for my $p (@$props) {
if ($p->{name} eq "maxEngines") {
$maxEngine = $p->{value};
last;
}
}
Or, if you know for sure that "maxEngines" always is the first array field, you can say
my $maxEngine = $license->{properties}[0]{value};
to retrieve the 42000.
