Read the file line for line and use a flag to indicate whether you want to collect lines or not, you could also call it a simple state machine:

my $errormatching=0;
my @errortext='';
while (<>) {
  if (not $errormatching) {
    $errormatching=1 if m{^\s*'Errors' =>};
  }
  else {
    if (not m{^\s*\]}) {
       push @errortext, $_;
    }
    else {
      process_error(@errortext);
      @errortext=();
      $errormatching=0;
    }
  }
}

UPDATE: Fixed typo where I used [ instead of ] in the regex
