SPUG: Can't use an undefined value as an ARRAY reference

Data::Dumper is your friend for dumping complex data structure and seeing there content.

You can add something to this extent:

use Data::Dumper;

print Dumper $call;
print Dumper $call->result();

I hope this helps.

Hi Luis,

This means that $call->result() is giving you undef as its return value, but
you are expecting a reference to an array instead.

List,

This line of code:

  my (@p) = $b->getRecentPosts(numposts=>20);

is giving me this error:

Can't use an undefined value as an ARRAY reference at
/usr/lib/perl5/site_perl/5.8.0/Net/Blogger/API/Core.pm line 199.


where the line 199 is this:

my @posts = ($call) ? (1,@{$call->result()}) : (0,undef);

But I cannot understand why is going on in here. Any idea what is going on
in here? or how can I fix this?

Thanks,

Luis
