Hi - I was updating this script at work in a totally different section to add an exception. When I went to test run it, I received an error: Experimental keys on scalar is now forbidden at line 339. I went to that part of the script and fixed it by dereferencing. my @result = keys $results->{$ip}; changed to my @result = keys %{$results->{$ip}}; However, when I re-ran the script, I got the error: Can't use an undefined value as a SCALAR reference at line 335. I then tried to change that part of the code by removing the ${} that surrounded $client->do_task(...) based on a suggestion from someone else. I have no idea about json and using it, and I have no idea about what this part of the code does. When I re-ran the script again, I then got the error: malformed JSON string, neither tag, array, object, number, string or atom, at character offset 0 (before "(end of string)") at line 334. I am now not sure if I fixed the Experimental Keys error correctly or not as I am not understanding why the other stuff is breaking when fixing it. Original code, without any fixes, is below

Any help in understanding these errors and how to correct would be appreciated. Thanks
