If you need placeholder here, but you don't have need for any
attributes, you may use `undef` here

my $Accomps = $dbh->selectall_hashref( $q, 'ID', undef, $Sid );

Here we actually don't need values of $Accomps-hashref, we just using
it as list to check out form values, so depending of your futher
needs, you may assign your specific value here, like, for example:

           $input_hash->{ $key } = 1;

What is on line 577 of your MyApp.pm?
