Hi,
Yes, I was using a ref with my dumper. When i don't do that I don't get $VAR1 =
\{ .
I am still getting an error when I dereference.
my $name = ${$hash_ref_decode}->{items}[0]{content};
say '$name'. $name;
The error is:
Not a SCALAR reference at todoist.pl line 79.
but it should be a scalar right? Am i missing something? When I dump the
$hash_ref I get:
$VAR1 = {
