<code>
my $array_ref = {};
push(@$array_ref, {});
</code>
The code above, which is part of your second example, gives an error because $array_ref = {} initializes your $array_ref to a hash ref which is not compatible as the first argument of push. It may be sort of symptomatic of your programming difficulties in that initializing $array_ref to a hash ref is confusing and just looks like code that is headed off in the wrong direction. I think your examples add more complication than needed and, for me, trying to simplify gives a result like:
<code>
use strict;
use warnings;
sub foo {
my %hash = ();
....
%hash = .... # key/values populated by some API
bar(\%hash);
}
sub bar {
my $hash_ref = shift;
my @arr_of_href = $hash_ref;
foreach my $i (.....) {
.... %some_hash initialized here for each iteration of the for loop
push (@arr_of_href, \%some_hash);
}
zzz(\@arr_of_href); # zzz() will do something with this array
}
</code>
